Latest Patents

Fukui holds a patent for an optical transmitter that automatically controls the biasing of an optical duobinary transmitter using a single-drive LN-MZ modulator. This technology involves the amplitude modulation of a low-frequency signal onto a voltage signal input into a Mach-Zehnder optical modulator. The optical output from the modulator is detected by an optical detection subsystem. In the bias control subsystem, the low-frequency signal component amplitude modulated onto the electrical signal is detected from the optical output. The DC bias voltage applied to the optical modulator is then controlled to either minimize or maximize the low-frequency signal component.
