Title:
OPTICAL FREQUENCY COM GENERATOR
Document Type and Number:
WIPO Patent Application WO/2003/010596
Kind Code:
A1
Abstract:
An optical frequency com generator comprises an oscillator (117) which oscillates a modulation signal with a predetermined frequency, an optical resonator (110) which consists of an incidence side reflector (112), an emission side reflector (113) parallel with each other and resonates light entered via the incidence side reflector (112), and an optical phase modulator (111). The optical phase resonator (111) comprises an electrooptical crystal the refractivity of which is varied by impressing an electric field, arranged between the incidence side reflector (112) and the emission side reflector (113), modulates the phase of light resonated by the optical resonator (110) according to the modulation signal supplied from the oscillator (117), and generates a side band centered around the frequency of the entered light at the interval of the frequency of the modulation signal. The emission side reflector (113) set a transmittance for every frequency according to the light intensity of the generated side band.
