GaAlAs p-i-n Junction Waveguide Modulator
Date of Original Version
Optical communications systems often require modulating elements which change the intensity, phase, or polarization of the light. A waveguide modulator has been fabricated in the form of a GaAlAs p-i-n heterostructure grown on the (110) crystallographic plane. The device rotates the plane of polarization of light as a function of the applied voltage. Monomode waveguiding and efficient modulation was achieved. The operation could be described with Jones matrices having voltage-dependent matrix elements. © 1983 IEEE
