Group Delay Control in Longitudinal Offset Coupled Resonator Optical Waveguides

P. Chamorro-Posada, F. J. Fraile-Peláez

We study the differential group delay that can be obtained in coupled micro-ring resonator waveguides with longitudinal offset couplers. Various devices based on this effect are pr…

Fast and slow light in zig-zag microring resonator chains

P. Chamorro-Posada, F. J. Fraile-Pelaez

We analyze fast and slow light transmission in a zig-zag microring resonator chain. This novel device permits the operation in both regimes. In the superluminal case, a new ubiquit…

A common model for superluminal propagation in absorbing atomic media and lossy metastructures

P. Chamorro-Posada, F. J. Fraile-Pelaez

We analyse the superluminal propagation of narrow-band pulses at resonances in dissipative media. The output waveform is an attenuated, undistorted, time-advanced version of the in…
