In this paper, we investigate the enhancement of Raman amplification bandwidth in silicon based photonic crystal waveguides with self-phase modulation (SPM) effect. The Maxwell equations are solved using finite difference time domain method considering two photon absorption, free carrier absorption, Kerr and SPM effects. We also studied the effects of shape, width and average power on the Raman amplification...
Self phase modulation in hollow waveguide filled with noble gases have been successfully used to produce ultra-broad bandwidths. The intense spectral phase distortions produced by self phase modulation have previously been compensated by prism pairs and adaptive pulse shaping. Here we demonstrate the generation of 4.8 fs, 200 muJ intense laser pulses by multiphoton intrapulse interference phase scan...
A simple system of an all-optical system for stopping and storing is proposed. A system consists of two microring and a nanoring resonators that can be integrated into a single system. The large bandwidth is generated by a soliton pulse within a Kerr-type nonlinear medium where an all-optical adiabatic and pulse bandwidth compression can be performed. The balance between the dispersion and nonlinear...
