RADIO-FREQUENCY SIGNAL REPETITION AND AMPLIFICATION USING PHASE-MODULATION INJECTION-LOCKED LASERS

摘要

A method and apparatus for regenerating a received radio frequency (RF) signal may mix the received RF signal with a first laser signal, and the result, or a filtered version thereof, may be used to injection-seed a second laser. The result may be mixed with the first laser signal, and the result may be detected to provide a regenerated version of the received RF signal.

主权项

1. A radio frequency (RF) signal regenerator comprising:
first and second lasers; a modulator configured to modulate a received RF signal onto an output signal of the first laser to obtain a seed signal; an injection arrangement configured to inject the seed signal into the second laser to obtain an injection-seeded signal as an output of the second laser; a combiner configured to combine an output of the first laser with the injection-seeded signal to obtain a combined signal; and a detector configured to detect an output RF signal from the combined signal.
