Claim 7:
8. 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 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; and

an optical demultiplexer for demultiplexing (a) a first of a plurality of different wavelengths of an optical comb source to form a first of the plurality of injection locking signals and (b) a second of a plurality of different wavelengths of an optical comb source to form a second of the plurality of injection locking signals;
each of the plurality of optical source generators further comprising a power splitter coupled with the optical circulator;
the plurality of optical source generators forming at least a first cascaded group and a second cascaded group;
a first optical source generator of the first cascaded group being coupled with the optical demultiplexer to receive the first of the plurality of injection locking signals, the power splitter splitting an optical output from the child laser to form the optical source output and one of the plurality of injection locking signals coupled to a second optical source generator of the first cascaded group; and
a first optical source generator of the second cascaded group being coupled with the optical demultiplexer to receive the second of the plurality of injection locking signals, the power splitter splitting an optical output from the child laser to form the optical source output and another one of the plurality of injection locking signals coupled to a second optical source generator of the second cascaded group.
