A transceiver comprises a transmitter including a light source, a modulator coupled to the light source, a driver that drives the modulator according to a set of driving conditions to cause the modulator to output optical signals based on light from the light source, and an output that passes first portions of the optical signals output by the modulator. The transceiver further comprises a first detector that detects second portions of the optical signals output from the modulator, and a receiver including a second detector that detects optical signals from an external transmitter.

Systems, devices, and methods for tuning transceivers

Embodiments are disclosed for generating an optical Pulse Amplitude Modulation 4-level (PAM-4) signal from bandwidth-limited duobinary electrical signals in a Mach-Zehnder modulator. An example system includes an MZM structure that comprises a first waveguide interferometer arm structure associated with a first semiconductor device and a second waveguide interferometer arm structure associated with a second semiconductor device. A polybinary electrical signal is applied to or between the first semiconductor device and the second semiconductor device to convert an input optical signal provided to the MZM structure into an optical PAM-4 signal.
