Ultrafast optical pulse compression using a semiconductor nonlinear Bragg reflector

Femtosecond optical pulse compression in a single-path reflection geometry using an InGaAs quantum well/InP/InGaAsP nonlinear Bragg reflector is demonstrated at a wavelength of 1500 nm. Reflected optical pulses from the nonlinear Bragg reflector was compressed due to soliton-like self-pulse-shaping process. Residual group velocity of the reflected pulses is compensated by a dispersive delay line and sub-100-fs pulse compression is realised.
