Title: Light modulator
Inventor: KIYOMOTO HIRONOBU
IPC: G02B6/12
Filed: 1990-11-30
Abstract: PURPOSE:To obtain a two-input two-output type light modulator which can be operated at a low operation voltage and has a high quenching ratio by providing an input light waveguide passage formed on a substrate, two output optical waveguides, a first and second directional joint parts, and a phase modulation part. CONSTITUTION:The incident light Pi is divided into two equal light portions by an input side 3dB coupler 2, and propagated to two optical waveguides 1A and 1B of a phase modulation part 1. At this time, the gap gm between the optical waveguides 1A and 1B is set larger than the optical waveguide gap gc of the 3dB coupler 2, and the generation of the light joint is prevented. Further, the optical waveguides 1A and 1B are constituted of the optical waveguide parts 11A, 12A, 11B and 12B having different optical guide passage width, and the generation of the connection of light is prevented by increasing the difference of the propagation constant of the opposed part, and the operation voltage is lowered by reducing the optical guide gap gm. Further, in order to obtain the high light quenching ratio, the propagation loss, etc., are made equal in both the optical waveguides 1A and 1B by forming two optical waveguide parts having different width in two optical waveguides 1A and 1B in the phase modulation part.
