Title: Optical modulator which has bias point adjusting function, and switch
Inventor: CHIBA AKIHITO
IPC: G02F1/035
Filed: 2009-02-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide an optical modulator which can easily obtain stable bias conditions.  <P>SOLUTION: The optical modulator uses directional couplers at a branch part (5) and a multiplexing part (6) of a main Mach-Zehnder (MZ) type waveguide (8). By using the directional coupler at an input/output section of the main MZ waveguide, when the voltage applied to a sub MZ electrode is changed, a bias voltage where light intensity of each output port becomes a minimum value is shifted by phase shift of the directional coupler. By utilizing this, it is possible to obtain stable bias conditions without controlling a voltage of a main electrode.  <P>COPYRIGHT: (C)2010,JPO&INPIT
