Analysis and simulation of ring resonators for slow and fast light devices applications

Hamidreza Khashei, Hassan Kaatuzian

In this paper we demonstrate, how fast and slow light phenomena in ring resonator can simultaneously be observed at a single frequency, using strongly coupled ring resonators. We also report on the design of a ring resonator with SOI technology that operate in optical wavelength 1.55 micron and have (one micro-ring) a factor for fast light ~22 picosecond (ps) and a factor for slow light ~12 ps with bandwidth ~100GHz with mixing angle (θ) 30 degrees, however depended on mixing angle and number of rings. Using light in a mixed polarization state, we show that fast and slow light can be obtained from a single incident wave packet. We simulate one micro-ring and extend our result to more micro-ring.In this paper we demonstrate, how fast and slow light phenomena in ring resonator can simultaneously be observed at a single frequency, using strongly coupled ring resonators.

Methods of slow light generation

Iraj Sadegh Amiri, Abdolkarim Afroozeh, H. Ahmad

This chapter presents the techniques of generating slow and fast pulse using micro-ring resonator (MRR). MRR systems made of different materials. Micro-ring device can be constructed with radius in the size of a micron. The chapter utilises the input power below and above threshold value to investigate the behavior of light pulse in term of linearity and nonlinearity. To generate slow light, series of ring resonators is used. In this method, the nonlinear effect of waveguide is neglected because of threshold power of nonlinear effect. Bright soliton and Gaussian beam can be used for three waveguide as input pulses. In this method chaotic signal can be canceled by neglecting nonlinear effects. All optical waveguide materials to generate slow and fast light should be dispersive. This means that the refractive index varies with wavelength. There are several ways to measure dispersion in materials.This chapter presents the techniques of generating slow and fast pulse using micro-ring resonator (MRR).

Slow and Fast Light through Weak Measurements of Spectral Superoscillations

Thomas Zacharias, Liran Hareli, Alon Bahabad

Abstract Slow and fast light are light pulses moving at group velocities slower or faster than the speed of light in vacuum. Current methods to achieve slow and fast light are based on strong dispersion attainable in resonant systems. By defining slow and fast light based on the arrival of the expectation value of the pulse in time, an alternative route for achieving slow and fast light is experimentally demonstrated where no dispersion engineering is needed and thus can be applicable to any medium and system where light is propagating. The method is based on the phenomenon of superoscillations and entails a weak measurement of the arrival time of a light pulse. The findings can be useful for applications in telecommunication, interferometry, and laser radars.Abstract Slow and fast light are light pulses moving at group velocities slower or faster than the speed of light in vacuum.
