Optical Frequency Comb Generator is an Electro-Optic (LiNbO3) modulator
inside a Fabry-Perot cavity. It generates thousands of sidebands (discrete
spectra) and a wide comb span (>6THz) modulated by microwave. An interval
between sidebands is completely equal to a modulation frequency. All of
components are passive and a center frequency is as same as a frequency
of input stabilized laser. It fully Covers C-band of DWDM optical communications.
Modulation frequency 10GHz(waveguide), 25GHz(waveguide)
as standard models are now on sale.

Principle of Optical Frequency Counter
Optical Comb of fm spacing is generated from the input stabilized laser of frequency f0. The laser-under-test with frequency fx generates beat signal of frequency fb with the k-th order of the comb sideband. The frequency fx is calculated by the equation fx=f0+k*fm+ fb.
Applications; Laser frequency stabilization, Phase locking for Tera-Hertz(THz) synthesis, Spectroscopy, Optical measurement, etc.
