Abstract

The existence of two polarization dependent band edges in InGaAs/InP quantum well material has been used to demonstrate single wavelength all-optical switching in a nonlinear guided wave Fabry-Perot resonator. The device had a single quantum well embedded in the optical waveguide and was characterized as a function of input pump power and laser wavelength using laser pulses of about 45 ps duration at a repetition rate of 82 MHz. A signal gain factor of over two was obtained for pump pulses of 1.2 pJ and the optimum operating wavelength of 1.51 µm was found to coincide with the heavy hole exciton absorption resonance.© 1995 American Institute of Physics.
