In this paper, we report a direct comparison between coupled resonator optical waveguides (CROWs) and photonic crystal (PhCWs), which have both been exploited as tunable delay lines. The two structures were fabricated on the same silicon-on-insulator (SOI) technological platform, with fabrication facilities evaluated under signal bit-rate conditions. We compare frequency- time-domain response of structures; physical mechanism underlying tuning delay; main limits induced by loss, dispersion,...

Abstract A century after the first optical cavity, coupled resonator waveguides (CROWs) were conceived as a new way to guide light on photonic chip. Controlling chains of resonators let propagate through, with reduced speed and enhanced intensity, boosting light‐matter interaction while keeping information undistorted: this was fascinating promise CROWs, but also one most ambitious challenges ever set for integrated optics. The decade history CROWs is discussed in review, from original idea...

Wave mixing inside optical resonators, while experiencing a large enhancement of the nonlinear interaction efficiency, suffers from strong bandwidth constraints, preventing its practical exploitation for processing broad-band signals. Here we show that such limits are overcome by new concept travelling-wave resonant four-wave (FWM). This approach combines efficiency provided propagation with wide-band conversion process. Compared conventional FWM in bare waveguides, it exhibits higher...
