[ThC2-2] Proposal and Verification of Auto Calibration Technique for Bias Control Circuit Connecting to Imperfect IQ-modulator

〇Hiroto Kawakami, Shoichiro Kuwahara, Yoshiaki Kisaka (NTT Corporation, Japan)

キーワード:Optical transmitter and receiver subsystems

We show that imperfection in an IQ-modulator degrades the accuracy of the auto bias control circuit connected to the modulator’s complementary port, and propose an auto calibration technique that can effectively suppress this degradation.
