Latest Patents

Uchida holds a patent for an optical transmitter. This technology provides a method to automatically control the biasing of an optical duobinary transmitter using a single-drive LN-MZ modulator. The invention 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. This allows for the control of a DC bias voltage applied to the optical modulator, ensuring that the low-frequency signal component is either minimized or maximized.
