Abstract: PROBLEM TO BE SOLVED: To provide two pairs of resonator structures of different length at each selected frequency by changing design of a conventional MFL WGR type laser. SOLUTION: A waveguide grating router is used as a filter for frequency control, and two paths slightly different in length at each selected frequency are configured for the router, forming a DiDomenico type laser which uses a pair of coupled cavities for frequency control. In one application, two pairs, comprising N numbers of optical amplifiers respectively, are used to form two resonation paths at each frequency. In another application, a part of an output power propagates a second path to form a second optical path.
