Abstract

We investigate the optical bistability and multistability in donor and acceptor quantum dots embedded in a nonlinear photonic crystal inside an optical ring cavity. It is found that the optical bistability and multistability can be easily controlled via adjusting properly the corresponding parameters of the system. The effect of the dipole–dipole interaction has also been included in the formulation, which leads to interesting phenomena. Our scheme opens the possibility to control the optical bistability and multistability in photonic materials doped with nanoparticles.

Switching from optical bistability to multistability in a coupled semiconductor double-quantum-dot nanostructure

Zhiping Wang, Benli Yu

We investigate the optical bistability (OB) and multistability in a coupled semiconductor double-quantum-dot nanostructure inside an optical ring cavity. It is found that the transition from OB to multistability or vice versa can be easily controlled via properly adjusting the corresponding parameters of the system. Our scheme opens the possibility to optimize and control all optical switching and all optical storage devices in a coupled semiconductor double-quantum-dot nanostructure.

Controlling the photoluminescence of acceptor and donor quantum dots embedded in a nonlinear photonic crystal

Mahi R. Singh, Chris Racknor, Daniel G. Schindel

We have studied energy transfer and photoluminescence in donor and acceptor quantum dots embedded in a nonlinear photonic crystal. The quantum dots are interacting with each other via the dipole-dipole interaction. The nonlinear photonic crystal modifies the dielectric constant of the hybrid system. Using the density matrix method, it is found that the energy transfer and photoluminescence in the donor quantum dot can be controlled by a pump field due to the nonlinearity of the photonic crystal. Additionally, our theoretical calculations agree with recent experiments. This hybrid system can be used to fabricate ultrafast switching and sensing nanodevices.

Optical multistability in 1D photonic crystal doped with carbon-nanotube quantum dot nanostructures

Ghahraman Solookinejad, Mohammad Payravi, Masoud Jabbari +2 more

Abstract The optical bistability (OB) and multistability (OM) in one-dimensional photonic crystals doped with carbon-nanotube quantum dots (CNT QDs) is theoretically investigated. Our investigations show that due to spin–orbit coupling in CNT QDs the threshold of optical bistability can be adjusted. Also, the switching from OB to OM, or vice versa, can be achieved by controlling the transverse magnetic field. Our proposed model can be used as a suitable structure based on CNT QDs for realizing all-optical switching devices. Moreover, we realize that the controlling of OB and OM can be done without changing the thickness of the layers.

Control of optical bistability and third-order nonlinearity via tunneling induced quantum interference in triangular quantum dot molecules

Si-Cong Tian, Ren-Gang Wan, Cunzhu Tong +6 more

The optical bistability of a triangular quantum dot molecules embedded inside a unidirectional ring cavity is studied. The type, the threshold and the hysteresis loop of the optical bistability curves can be modified by the tunneling parameters, as well as the probe laser field. The linear and nonlinear susceptibilities of the medium are also studied to interpret the corresponding results. The physical interpretation is that the tunneling can induce the quantum interference, which modifies the linear and the nonlinear response of the medium. As a consequence, the characteristics of the optical bistability are changed. The scheme proposed here can be utilized for optimizing and controlling the optical switching process.

Manipulating transmission and reflection properties of a photonic crystal doped with quantum dot nanostructures

Ghahraman Solookinejad, M. Panahi, Elnaz Ahmadi Sangachin +1 more

The transmission and reflection properties of incident light in a defect dielectric structure is studied theoretically. The defect structure consists of donor and acceptor quantum dot nanostructures embedded in a photonic crystal. It is shown that the transmission and reflection properties of incident light can be controlled by adjusting the corresponding parameters of the system. The role of dipole–dipole interaction is considered as a new parameter in our calculations. It is noted that the features of transmission and reflection curves can be adjusted in the presence of dipole–dipole interaction. It is found that the absorption of weak probe light can be converted to the probe amplification in the presence of dipole–dipole interaction. Moreover, the group velocity of transmitted and reflected probe light is discussed in detail in the absence and presence of dipole–dipole interaction. Our proposed model can be used as a new all-optical devices based on photonic materials doped with nanoparticles.
