METHOD FOR CONTROLLING OPTICAL CHARACTERISTIC OF WAVEGUIDE TYPE OPTICAL COMPONENT, WAVEGUIDE TYPE OPTICAL COMPONENT, AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for controlling optical characteristics of a waveguide type optical component by which the optical characteristics can be controlled while controlling the induction quantity of double refraction in the refractive index control of a waveguide by using light induction type refractive index changes, and to provide the waveguide type optical component controlled in optical characteristics of polarization-independent and polarization-dependent and its manufacturing method.;SOLUTION: In the method for controlling optical characteristics of the waveguide type optical component by using light induction type refractive index changes, the waveguide type optical components has a Mach-Zehnder interferometer arranged in an optical circuit and two arms of the Mach-Zehnder interferometer are irradiated with ultraviolet light of polarized waves of different directions.;COPYRIGHT: (C)2005,JPO&NCIPI
