OPTICAL MODULATOR, OPTICAL TRANSMITTER, AND BIASVOLTAGE ADJUSTMENT METHOD OF OPTICAL MODULATOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18384506 titled 'OPTICAL MODULATOR, OPTICAL TRANSMITTER, AND BIASVOLTAGE ADJUSTMENT METHOD OF OPTICAL MODULATOR
Simplified Explanation
The present invention relates to an optical modulator with the capability of adjusting bias voltages based on monitor signals from photodetectors. In a third Mach-Zehnder type optical modulator, first and second MZ optical modulators are provided on separate arms, each monitored by a photodetector that outputs a monitor signal. A bias voltage generation unit independently adjusts bias voltages provided to the MZ optical modulators based on the monitor signals.

Original Abstract Submitted
An object is to provide an optical modulator capable of adjusting a bias voltage with a simple signal measurement. In a third Mach-Zehnder type optical modulator, a first MZ optical modulator is provided on one arm and a second MZ optical modulator is provided on the other arm. A first photodetector monitors a first output light from the first MZ optical modulator and output a first monitor signal. A second photodetector monitors a second output light from the second MZ optical modulator and output a second monitor signal. A third photodetector monitors a third output light from the third MZ optical modulator and output a third monitor signal. a bias voltage generation unit independently adjusts first to third bias voltages provided to the first to third MZ optical modulators based on the first to third monitor signals, respectively.
