TL;DR: It is found that the ratio of nonlinearity and dispersion linearizes the pulse chirp, reducing the spectral oscillations caused by self-phase modulation alone and giving rise to a nonlinear transfer function suitable for all-optical regeneration of high data rate signals.

TL;DR: In this article, a planar chalcogenide waveguide is demonstrated to be able to perform radio-frequency spectral measurements with a terahertz bandwidth and high bit-rate tests show that the chip-based system is potentially useful for ultrafast signal processing.

TL;DR: This work demonstrates optical performance monitoring of in-band optical signal to noise ratio (OSNR) and residual dispersion, using slow-light enhanced optical third harmonic generation (THG) in a compact 2D silicon photonic crystal waveguide, and opens the door for slow light to play a key role in ultra-high bandwidth telecommunications systems.

TL;DR: In this article, a summary of recent experiments showing how various nonlinear phenomena are enhanced due to slow light in silicon photonic crystal waveguides is presented, including self-phase modulation (SPM), two-photon absorption (TPA), free-carrier related effects, and third-harmonic generation.

TL;DR: In this paper, a planar rib waveguide with nonlinearity up to 2080 W-1ldr km-1 and losses as low as 0.05 dB/cm has been developed to enable high-speed all-optical signal processing in compact, low-loss optical devices through the use of ultra fast Kerr effect.
