Abstract
The frequency of an optical signal output from an optical source is controlled while maintaining the polarization of the signal by guiding the signal with either a polarization maintaining optical fiber or an integrated optics waveguide. A portion of the signal output from the light source is input to the light guiding structure. The optical signals are phase modulated, and an electrical signal indicative of the intensity of an optical signal output from the polarization maintaining light guiding device is applied to the optical source for controlling the frequency of the optical signal output therefrom.
