ABSTRACT:
A compact multiwavelength laser arrangement includes a reflective waveguide grating combined with two arrays of reflecting waveguide elements located in separate focal regions formed by the grating. The laser uses a folded imaging arrangement with nonoverlapping focal regions that eliminates unwanted resonances of previous reflective arrangements. The laser's advantages over existing transmissive laser arrangements include reduced size, faster response time, and increased number of wavelengths.
