Abstract

This study has been focused on the linear and nonlinear behavior and investigative in single-ring resonator. Optical fiber ring resonators have great interest due to different applications, especially in communication, secured communication, slow light, fast light and light storage in optical buffers. There are many proposed applications of optical ring resonators. Optical fiber ring resonators can be readily constructed from standard optical fiber components, which allow their properties to be studied in a systematic manner. In this paper, we describe our studies of the optical transmission, intensity, shift phase and group delay characteristics of a family of such devices. In this case, Gaussian beam has been used as an input pulse inside to microring resonators. In this paper, transmission, intensity, shift phase and group delay characteristics of device have been investigated. It has been compared together in different coupling coefficients in frame of linear and nonlinear.

Superluminal and slow light in eye-like ring resonator

Yundong Zhang, Kai Ma, Yongfeng Wu +3 more

We investigate the phase and group delay in eye-like ring resonator with the effect of different coupling coefficients and attenuation factors. The eye-like structure is composed of two bus waveguides coupling with the outer ring and the two rings coupling together which have the same perimeters. The eye-like ring resonator has two outputs which have different transmission characteristics. In this paper, we measure the group delay of the two outputs through changing the coupling coefficients and the attenuation factors of the inner and the outer ring. The result shows that the two outputs have reverse group delay (superluminal and slow light) which will have potential use in slow light fiber, optical buffers and optical switches.

COUPLER-LOSS AND COUPLING-COEFFICIENT DEPENDENCE OF BISTABILITY AND INSTABILITY IN A FIBER RING RESONATOR: NONLINEAR BEHAVIORS

Preecha P. Yupapin, P. Saeung, W. Suwancharoen

In this paper we demonstrate the dynamic simulation of light traveling in a nonlinear fiber optic ring resonator (FORR) with a single coupler. The mathematical relations describing the nonlinear characteristics of the FORR are derived from light transmission theory in linear optical systems. Optical nonlinear phenomena such as bifurcation and chaos are investigated for optical bistability and the Ikeda instability. It is found that for the Ikeda instability of light inside a FORR, the ring-cavity lifetime is much longer than the Kerr-effect response time of the fiber ring. Transmission curves of bistability and instability are shown as a function of the coupler insertion losses (γ) and the coupling coefficients (κ).

Simultaneous observation of fast and slow light propagation in a single fiber ring resonator

Geng Li, Yundong Zhang, Xuenan Zhang +3 more

We have observed the fast and slow light propagation in a single fiber ring resonator simultaneously. The two outputs of this structure behave different transmission characteristics that result in opposite dispersion performance. The transmission spectral and group delay of two outputs are demonstrated experimentally and theoretically.

Fast, Slow, Stopping, and Storing Light

Preecha Yupapin, Jalil Ali

The behavior of light in nano/micro optical devices has shown promising results which can be useful for much fundamental and applied research, especially in nanoelectronics. In particular, with the manipulation of fast and slow light, Pornsuwancharoen and Yupapin [1] have proposed the use of a simple device called a microring resonator to perform such behavior, in which the four different behaviors of light, that is, fast, slow, stopping, and storing of light are investigated using a ring resonator. Nowadays, stopping or cooling a light beam has become a promising technique for atom/molecule trapping investigations (using static or dynamic tweezers), especially after the announcement of the 2012 Nobel Prize in Physics for the whispering gallery modes [2,3]. There are two more kinds of devices that are used to trap light beams: the use of microcavity arrays performed by Yanik and Fan [4], and the nonlinear microring resonator by Yupapin and Pornsuwancharoen [5] for stopping light (laser beam). Ang and Ngo have also recently done experiments in slowing light in microresonators using a microring system [6]. This concept is a concrete backbone for many applications.

Integrated Micro-Ring Photonics: Principles and Applications as Slow Light Devices, Soliton Generation and Optical Transmission

Iraj Sadegh Amiri, Abdolkarim Afreezeh, H. Ahmad

Micro-ring resonators (MRRs) are employed to generate signals used for optical communication applications, where they can be integrated in a single system. These structures are ideal candidates for very large-scale integrated (VLSI) photonic circuits, since they provide a wide range of optical signal processing functions while being ultra-compact. Soliton pulses have sufficient stability for preservation of their shape and velocity. Technological progress in fields such as tunable narrow band laser systems, multiple transmission, and MRR systems constitute a base for the development of new transmission techniques. Controlling the speed of a light signal has many potential applications in fiber optic communication and quantum computing. The slow light effect has many important applications and is a key technology for all optical networks such as optical signal processing. Generation of slow light in MRRs is based on the nonlinear optical fibers. Slow light can be generated within the micro-ring devices, which will be able to be used with the mobile telephone. Therefore, the message can be kept encrypted via quantum cryptography. Thus perfect security in a mobile telephone network is plausible. This research study involves both numerical experiments and theoretical work based on MRRs for secured communication.

Dynamic transmission properties of a nonlinear fiber ring resonator

Kazuhiko Ogusu, Hidenori Shigekuni, Yasuo Yokota

We present a method for calculating the dynamic input–output characteristics of a nonlinear fiber ring resonator caused by a change in input intensity. It is based on an original method developed by Bischofberger and Shen [Phys. Rev. A 19, 1169 (1979)] to study a transient nonlinear Fabry–Perot resonator. We treat a double-coupler fiber ring resonator, in which two types of optical bistability (transmission bistability and reflection bistability) are available and present the illustrative numerical results for a few cavity parameters. This analysis will be useful for a future experimental verification of optical bistability in fiber ring resonators and for the design of fiber bistable devices.
