Abstract
An injection locked transmitter for an optical communication network includes a primary seed laser source input substantially confined to a single longitudinal mode, an input data stream, and a laser injected modulator including at least one secondary laser having a resonator frequency that is injection locked to a frequency of the single longitudinal mode of the primary seed laser source. The laser injected modulator is configured to receive the primary seed laser source input and the input data stream, and output a laser modulated data stream.
Claims20
A transceiver for an optical network, comprising:
- a first child laser;
- a child modulator configured to injection lock the first child laser to a parent frequency of a single mode of a laser source signal;
- and
- an input portion configured to (i) receive a first optical modulated signal on a first coherent tone of the laser source signal;
- (ii) receive a first optical unmodulated signal on a second coherent tone of the laser source signal, and (iii) route the first optical unmodulated signal on the second coherent tone to the child modulator,
- wherein a frequency of the second coherent tone is held constant to a frequency of the first coherent tone,
- wherein the child modulator is further configured to output a second optical modulated signal on the second coherent tone.
