Abstract
An optical device for use in generating a high frequency optical signal includes a light source for generating a pumping light beam, a first oscillator for generating a first light beam with a plurality of modes by using the pumping light beam, an optical element for selecting a first mode from the modes, a second oscillator for generating a second light beam of a second mode by using the selected first mode; and an optical coupler for coupling the selected first mode to the second mode to induce a beat phenomenon therebetween. In the optical device, the first oscillator generates the high frequency optical signal by the beat phenomenon.
