Classification: CPC H | IPC H

Claim 0:
1. Coherent optical injection locking (COIL) system, comprising:
a plurality of optical source generators each having:
a child laser; and
an optical circulator coupled with the child laser to direct one injection locking signal of a plurality of injection locking signals to the child laser to cause the child laser to generate an optical source output that replicates the one injection locking signal,
a first of the plurality of optical source generators receiving a single wavelength optical source as the one injection locking signal, the first of the plurality of optical source generators further comprising a first power splitter coupled with the respective optical circulator to split a first optical output from the respective child laser to form the respective optical source output and a second of the plurality of injection locking signals, wherein the second of the plurality of injection locking signals is fed into a second of the plurality of optical source generators.
