PROBLEM TO BE SOLVED: To provide an external resonator semiconductor laser and a method for fabrication thereof. SOLUTION: The external resonator single mode laser is disclosed in which a short optical path length for the optical resonator (for example, from about 3mm to 25mm) provides sufficient spacing of a plurality of longitudinal modes thereby allowing a single wavelength selective element such as microfabricated etalon, to provide a single mode of operation, and optionally a selectable mode of operation.
