Optical frequency generator
First Claim
1. An optical frequency generator, comprising:
- a reference light source;
an optical comb generator for generating a plurality of optical frequencies including a center frequency and comprising a frequency modulated light source and an optical non-linear component for receiving output light from the frequency modulated light source;
means for combining the output of the reference light source and of the optical comb generator for generating a control signal for modulating the frequency of the frequency modulated light source;
a frequency transmitter for generating an output signal for modulating the frequency of the frequency modulated light source;
an electronic control for setting the frequency of the frequency transmitter;
whereby the frequency modulated light source and the optical non-linear component generate a plurality of side bands relative to the center frequency, the frequency of the side bands being a multiple of the frequency of the output signal from the frequency transmitter.

Abstract
An optical frequency generator provided with an optical comb generator for generating a plurality of frequencies including a central frequency and side bands spaced by a frequency transmitter. The central frequency is adjustably combined with the spectral component of a reference light source. Modification of frequency differences between the central frequency and the reference light source and modification of the transmission frequency of the frequency transmitter displaces the frequency comb of the comb generator or alters its spectral width. A heterodyne receiver connected to the output of the comb generator and a test light source of unknown frequency is provided for determining the frequency of the latter.
