Analysis and fabrication of GaInAs/InP MQW graded refractive index‐type optical deflector

Abstract

SUMMARYA new type of optical deflector with a graded refractive index region is proposed. For this device, two types of structure, a multielectrode type and a comblike electrode type, have been numerically analyzed using the finite difference beam propagation method to show results such as the dependence of the deflection angle and the deflection efficiency on the structure. We fabricated this optical deflector using a GaInAs/InP MQW structure, and we confirmed the fundamental optical deflection and the wavelength dependence of the device. © 1999 Scripta Technica, Electron Comm Jpn Pt 2, 82(12): 2129, 1999
