Steering characteristics of GaInAs/InP MQW comb-type waveguide optical deflector

New type optical deflector with graded refractive index region has proposed. For this device, two types structure that are multi electrode type and comb like electrode type have been numerical analyzed using Finite Difference Beam Propagation Method, and have shown the structural dependence on the deflection angle and the deflection efficiency, etc. We fabricated this optical deflector using GaInAs/InP MQW structure, and we confirmed the fundamental optical deflector using GaInAs/InP MQW structure, and we confirmed the fundamental optical deflection and the wavelength dependence of the device.
