Abstract
Single frequency laser source phase noise constitutes a limitation in single-mode optical fiber coherent detection systems such as heterodyne communication receivers and optical fiber interferometric sensors. We investigate the phase noise affecting the beat photocurrent produced by the coherent detection of a single frequency laser field with a time-delayed and frequency-shifted image of itself in a heterodyne interferometer. The photocurrent spectrum is discussed as a function of the source lineshape and interferometer decorrelation time. An experimental study is retorted consisting of a single-mode fiber Mach-Zender interferometer employing a single-frequency laser and an acousto-optical modulation for frequency-shifting one of the interferometer arms. Results are in good agreement with theory.
