Simultaneous observation of superluminal and slow light propagation in a nested fiber ring resonator

Jinfang Wang, Yundong Zhang, Jing Zhang +3 more

We observe both superluminal and slow light propagation simultaneously in a nested fiber ring resonator. The two outputs of the resonator exhibit different absorption characteristics that produce opposite dispersion performance. The transmission spectra of two outputs are demonstrated experimentally for a variety of coupler settings. In particular, the group delays of the resonator for various values of the coupling coefficients are demonstrated theoretically and experimentally. We also discuss potential applications of the resonator.We observe both superluminal and slow light propagation simultaneously in a nested fiber ring resonator.

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.

SLOW AND STOPPED LIGHT 'Slow' and 'fast' light in resonator-coupled waveguides

John E. Heebner, Robert W. Boyd

We describe a device constructed of a sequence of microresonators coupled to an optical waveguide. The influence of these resonators is to enhance nonlinearities and to induce strong dispersive effects, leading to exotic optical properties including slow and superluminal group velocities of propagation.

Slow and fast light propagation in erbium-doped fiber

Nikolay N. Lepeshkin, Aaron Schweinsberg, Matthew S. Bigelow +2 more

We study propagation of light pulses and modulation in an Er-doped fiber in the regimes of anomalously slow and superluminal group velocities. The pulses experience either delay or advancement depending on the pump power.

Fast and slow light in zigzag microring resonator chains

Pedro Chamorro‐Posada, Francisco Javier Fraile-Pelaez

We analyze fast- and slow-light transmission in a zigzag microring resonator chain. In the superluminal case, a new light-transmission effect is found whereby the input optical pulse is reproduced in an almost-simultaneous manner at the various system outputs. When the input carrier is tuned to a different frequency, the system permits to slow down the propagating optical signal. Between these two extreme cases, the relative delay can be tuned within a broad range. We propose, and analyze numerically, a laser-array configuration for the stable operation of active devices.We analyze fast- and slow-light transmission in a zigzag microring resonator chain.
