1. An optical full-field transmitter for an optical communications network, the transmitter comprising:
a parent laser source configured to provide a narrow spectral linewidth for a primary laser signal;
a first child laser in communication with a first amplitude data source, the first child laser configured to modulate the first amplitude data source onto an output first amplitude-modulated optical signal; and
a first phase modulator in communication with a first phase data source and the first amplitude-modulated optical signal, the first phase modulator configured to implement phase modulation on the first amplitude-modulated optical signal to output a first two-stage full-field optical signal,
wherein the parent laser source has a structure based on a III-V compound, and
wherein the amplitude modulation by the first child laser is orthogonal to the phase modulation by the first phase modulator.
