Controlling an optical transmitter that supports multiple modulation formats and baud rates

摘要

A device receives a modulation format and a baud rate for transmission of an optical signal, and generates optical signals based on the modulation format and the baud rate. The device generates quadrature-delay-interferometer signals based on the optical signal, the modulation format, and the baud rate, and generates a particular optical signal with a particular wavelength for the modulation format and the baud rate. The device determines whether a point of the quadrature-delay-interferometer signals is associated with the particular wavelength of the particular optical signal, and sets or adjusts the particular wavelength of the particular optical signal for the modulation format and the baud rate based on whether a point of the quadrature-delay-interferometer signals is associated with the particular wavelength of the particular optical signal.
