In this letter, a new design of microring resonator device is proposed which can be used to generate four forms of light simultaneously on a chip, while the storing and harvesting of trapped atoms/molecules can also be available. The proposed device is made up of silica and InGaAsP/ InP with linear optical add-drop filter incorporating two nonlinear micro/nano rings on both sides of the center ring (add-drop filter). This particular configuration is known as a “PANDA” ring resonator [7] as shown in figure1. Light pulse, for instance, Gaussian, bright and dark solutions are fed into the system through different ports such as add port and through port. By using the practical device parameters, the simulation results are obtained using the Opt wave and MATLAB programs. Results obtained by both analytical and numerical methods show that many applications can be exploited. In application, when the practical device parameters are used, then such device can be fabricated and implemented in the near future. The proposed system can be used for many applications, especially, when the device is coated by a metallic material [8]. The applications such as atom/molecule transportation, molecule/atom antenna, atomic/ molecular automata, atom/molecule electronic devices, cells/atom distributed sensors, cells/atom radio, cells communications, micro Faraday cage, molecular/atom storage and logistics, atom/molecule trapping (storage) or cooling, everlasting atom/molecule investigation atomic/molecular storage for quantum gate or computer application, storm search and navigator sensors, magnetic/spin networks, magnetic net, micro plasma source, 3-D flat panel device and large cooling area (volume) can be constructed in the same way as a single device. In this work one of them is demonstrate. Under the stopping and storing condition, the system is considered as the storage unit, where atom or molecule can be trapped by the whispering gallery light beam at the center. The whispering gallery mode result is obtained by using the Optiwave program as shown in figure 2. The ring material is InGaAsP/ InP, where the device parameters are given in figure caption. By using the MATLAB program, the whispering gallery modes of four state of light i.e. fast, slow, stopping and storing can be generated and controlled simultaneously on-chip as shown in figure 3. The storing stage can be seen easily, while the stopping condition can be observed and the following conditions satisfied: (i) the center signal is lost in time between fast and slow signals or (ii) there is no movement among trapped particles or molecules i.e. the exchange of angular momentum introduces the conservation of angular momentum, where the combination of scattering and gradient forces is balanced under the adiabatic process.

Whispering gallery modes (WGMs) of waves in nature such as electromagnetic wave, sound wave, and matter wave have shown interesting results, which can be useful for fundamental studies and applications in optoelectronics and nanoelectronics, especially after the announcement of the 2012 Nobel Prize in Physics for WGMs [1,2], where the authors confirmed that atoms can be trapped (stopped) by using WGMs in a microsphere. However, there are two more kinds of devices that can be used to trap light beams (atoms); the use of microcavity arrays performed by Yanik and Fan [3], and a nonlinear microring resonator by Yupapin and Pornsuwancharoen [4] for stopping light. Recently, Ang and Ngo [5] have also done experiments with slowing light in microresonators using a microring system. In this article, a new design of microring resonator device is proposed, which can be used to generate four forms of light simultaneously on a chip, whereas the storing and harvesting of trapped atoms/molecules can also be available. The proposed device is made up of silica and InGaAsP/InP with linear optical add-drop filter incorporating two nonlinear micro/nano rings on both sides of the center ring (modified add-drop filter). This particular configuration is known as a PANDA ring resonator [6] as shown in Figure 14.1. Light pulse, for instance, Gaussian, and bright and dark solitons are fed into the system through different ports such as an add port and through port. By using the practical device parameters, the simulation results are obtained using the Optiwave and MATLAB programs. Results obtained by both analytical and numerical methods show that many applications can be exploited. In application, when the practical device parameters are used, then such a device can be fabricated and implemented in the near future.
Past and slow light behaviors are the interesting aspects of light which can be useful for many fundamental and applied researches. Pornsuwancharoen and Yupapin et al. [1] have proposed the use of a simple device called “microring resonator” to perform such behaviors. In this research work, the four different behaviors of light i.e., fast, slow, stopping and storing of light where investigated using a ring resonator. Nowadays, stopping or cooling light beam has become the promising technique for atom/molecule trapping investigations (using static or dynamic tweezers), especially, after the announcement of Nobel Prize 2012 in Physics on the whispering gallery modes [2, 3]. There are two more kinds of devices that can be used to trap light beams, the use of microcavity arrays performed by Yanik and Fan [4], and nonlinear microring resonator by Yupapin and Pornsuwancharoen [5] for stopping light (laser beam). Nanyang Technological University scientists have also done experiment to slowing the light in microresonators using a microring system recently [6]. This concept is a concrete backbone for many applications.

A generation of optical capsules and tweezers within a modified optical add-drop filter known as PANDA ring resonator with a new concept is proposed. By using dark and bright solitons, the orthogonal tweezers can be formed within the system and observed simultaneously at the output ports. Under the resonant condition, the optical capsules and tweezers generated by dark and bright soliton pair corresponding to the left-hand and right-hand rotating solitons (tweezers) can be generated. When a soliton is interacted by an object, an angular momentum of either bright or dark tweezers is imparted to the object, in which two possible spin states known as tweezer spins are exhibited. Furthermore, an array of molecular capsules and spins, i.e., trapped molecules can be generated and detected by using the proposed system, which can be used to form large scale tweezer or capsule spins. In application, the trapped molecules can be moved and rotated securely to the required destinations, which can be useful for many applications, especially, in medical diagnosis, therapy and surgery.
In this paper, we have shown that the two components (TE and TM waves) of polarized light are manipulated by using the orthogonal soliton pair within a PANDA ring resonator known as a dark-bright soliton pair. In operation, the orthogonal soliton sets can be generated by using the system. The optical field is fed into the ring resonator system, which is controlled by an optical switch by using a single microring. To form the initial spin states, the magnetic field is induced by an aluminum plate (Al) coupled on AlGaAs waveguides for optoelectronic spin-up and - down states. The optoelectronic spin is formed by using the TE and TM wave components. In this manipulation, the electromagnetic radiation is formed by using the orthogonal soliton pulses. In fact, they are photons, which behave like elementary particles. Hence, the spin axis of photon is always parallel to its direction of motion. Many orthogonal sets are also available and existed, in which the spin conservation of many particles is maintained for large scale system use. Therefore, for future applications, the use for high performance storage, low power magnetic logic, quantum logic, quantum gate, nano antenna, nano radio, and applications of spintronic sensing can be realized based on realistic device parameters.
Optical buffer is recognized as an essential component in a wavelength router, in which packets of data can be stored for resolving packet contention problem and also to delay the outgoing packets [1-2]. In practice, optical router patents have been proposed and recorded [3-5], which can be useful for various applications. Recently, promising techniques of microscopic volume trapping and transportation within an add/drop multiplexer have been reported in both theory [6]and experiment [7], respectively. The transporter in these techniques is known as an optical tweezer. The technique for generating optical tweezers has become a powerful tool for manipulating of micrometer-sized particles. Useful static tweezers have now been well recognized and realized. The use of dynamic tweezers has also been realized in practical works [8-10]. Schulz et al. [11] have shown that trapped atoms between can be transported between two optical potentials. Optical tweezers use forces exerted by intensity gradients in strongly focused beams of light to trap and move nanoscopic volumes of matter. During the movement, another combination of forces is induced between photons due to their interactions caused by photon scattering effects. The field intensity can also be adjusted and tuned to the desired gradient field and scattering force so that the suitable trapping force can be formed. Thus, by configuring the appropriated force for the transmitter/ receiver part, nanoscopic particles can be transported over a long distance. In this chapter, the methods for generating the dynamic optical tweezers/vortices using a dark soliton, a bright soliton and a Gaussian pulse propagating within an add/drop optical multiplexer with two nanoring resonators (PANDA ring resonator) will be discussed. The dynamic behaviors of a soliton and Gaussian pulses are well described. [12]. By using the proposed system, the transceiver can be integrated to form a single device. The transceiver can be used to transport nanoscopic volumes of matter [13], especially, molecules in liquid core waveguide [14, 15], drugs, and DNA, where a buffer is needed before the substance reaches its destination.
