Claim 12:
13. An injection locking method for multiple optical sources, comprising:
receiving a single optical source;
injection locking a plurality of optical source generators using the optical source;
generating, at each of the plurality of optical source generators, an optical source output having optical characteristics the same as the optical source;
demultiplexing at least a first wavelength and a second wavelength of the optical source into a respective first injection locking signal and a second injection locking signal;
feeding, via a first optical circulator of a first optical source generator of the plurality of optical source generators, the first injection locking signal into a first resonator of a first child laser of the first optical source generator to generate a first optical output at the first wavelength;
splitting the first optical output, using a first optical power splitter of the first optical source generator, into a first optical source output and a first injection locking output;
feeding, via a second optical circulator of a second optical source generator of the plurality of optical source generators, the first injection locking output into a second resonator of a second child laser of the second optical source generator to generate a second optical output at the first wavelength;
feeding, via a third optical circulator of a third optical source generator of the plurality of optical source generators, the second injection locking signal into a third resonator of a third child laser of the third optical source generator to generate a third optical output at the second wavelength;
splitting the third optical output, using a second optical power splitter of the third optical source generator, into a third optical source output and a second injection locking output; and
feeding, via a fourth optical circulator of a fourth optical source generator of the plurality of optical source generators, the second injection locking output into a fourth resonator of a fourth child laser of the fourth optical source generator to generate a fourth optical output at the second wavelength.
