Abstract
A dual optical frequency comb generator incudes a semiconductor substrate, a first optical frequency comb laser light source including a first resonator, a second optical frequency comb laser light source including a second resonator and differing in repetition frequency of optical pulses from the first optical frequency comb laser light source, two or more outputters including first and second outputters, a first optical waveguide connecting the first optical frequency comb laser light source with the first outputter, a second optical waveguide connecting the second optical frequency comb laser light source with the second outputter, and a third optical waveguide that branches off from the first optical waveguide and joins the second optical waveguide. The first optical frequency comb laser light source, the second optical frequency comb laser light source, the two or more outputters, and the optical waveguides are integrated on the semiconductor substrate.
