摘要

PROBLEM TO BE SOLVED: To effectively prevent or reduce the deterioration or decrease of optical characteristics due to that the angle of incidence of incident light is different from a predetermined angle of incidence or varied in a plane optical modulating element using multi-layered film reflecting layers as an etalon.;SOLUTION: The plane optical modulating element which has an ON/OFF layer 13, made of a material varying in refractive index with an electric signal, in a resonator composed of multi-layered film reflecting layers 11 and 12 has a control layer 14, applicable with a voltage independently of the ON/OFF layer 13 and made of a material varying in refractive index with an electric signal, in the resonator in addition to the ON/OFF layer 13.;COPYRIGHT: (C)2006,JPO&NCIPI
