英文摘要 | A phase noise detection apparatus comprises a laser beam, an optical resonator coupled to the laser beam at a coupling point and a photodetector receiving light from the laser beam. The laser beam is preferably guided in a waveguide. The laser beam and the resonator coupled to the laser beam convert phase noise of light transported by the laser beam prior to the coupling point into intensity noise of light transported by the laser beam immediately after the coupling point. The intensity noise after the coupling point is generated according to the phase noise prior to the coupling point. The intensity noise is converted into an electrical signal by the photodetector. The electrical signal generated by the photodetector is sent through a first signal path and a second signal path such that the first signal path transports a signal substantially proportional to the intensity noise and such that the signal is integrated in an integrator in the second path. The relative gain of the two signal paths can be adjusted and the overall gain of the signal path is preferably such that the optical phase modulator at least partially cancels said phase noise in the optical domain. |
