Power Efficient Multi-Format Optical Transmitters

An apparatus for generating a processed optical signal includes a first laser configured to emit a first optical signal in response to a first drive signal. The first optical signal has a first phase shift depending on a first integrated amplitude of the first drive signal. The apparatus also includes a spectral-temporal filter, in optical communication with the first laser, to change a first spectral profile and a first temporal profile of the first optical pulse so as to generate the processed optical signal. Replacing a conventional continuous-wave (CW) laser and external modulation with filter-based modulation can achieve the same or better performance without high-fidelity low-noise input signals.
