Latest Patents

Honzawa holds a patent for an optical transmitter that focuses on automatically controlling the biasing of an optical duobinary transmitter using a single-drive LN-MZ modulator. This technology involves amplitude modulating a low-frequency signal onto a voltage signal input into a Mach-Zehnder optical modulator. The optical output from the modulator is then 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 controlled to either minimize or maximize the low-frequency signal component.
