Abstract
Vibration causes mechanical distortions in fiber-optic transmission lines that induce phase fluctuations. A scheme is described which enables electronic cancellation of vibration-induced phase noise in an optical fiber wound on a spool. We report 20 dB or more cancellation of vibration-induced noise using feed-forward noise control . The scheme is also applied to an optoelectronic oscillator (OEO). The OEO has emerged as an excellent low-noise source that rivals the best electronic (RF) oscillators over broad offset frequencies. However, close-to-carrier spectral purity of an OEO is mostly degraded by the vibration-induced phase fluctuations in optical fibers when the temperature is held constant. Implementation of feed-forward noise control in fiber in an OEO has shown almost an order of magnitude improvement in the vibration sensitivity of the oscillator.
