Arbitrary wavelocking of an optical transmitter using embedded data sequences

An optical system, comprising:

• an optical transmitter;
• and
• a controller configured to:
• determine a particular wavelength for a channel of the optical transmitter;
• cause the optical transmitter to transmit a first optical signal with a first data sequence that is determined based on the particular wavelength;
• determine a first optical power that is generated based on the first optical signal and the first data sequence;
• cause the optical transmitter to transmit a second optical signal with a second data sequence that is determined based on the particular wavelength;
• determine a second optical power that is generated based on the second optical signal and the second data sequence;
• calculate a power difference between the first optical power and the second optical power;
• and
• cause the particular wavelength for the channel to be modified based on the calculated power difference.
