Abstract
Optical properties of InP/InGaAs nonlinear Bragg reflector are investigated by means of linear reflectance spectroscopy and ultrafast nonlinear reflectance measurements. The reflectance spectrum of InP/InGaAs nonlinear Bragg reflector is dominated by optical absorption enhanced by multiple reflection in Bragg reflector. Ultrafast reflectivity of InP/InGaAs nonlinear Bragg reflector is characterised by femtosecond pump-probe measurements. The ultrafast reflectivity is caused by absorption saturation and its recovery via carrier relaxation which are enhanced in Bragg reflector. Wavelength dependence of the ultrafast reflectivity is measured and explained due to carrier-carrier scattering.
