英文摘要	A digitally tunable laser source, a tapered waveguide, a lensed waveguide, a tunable laser and methods for making and tuning these devices are described. The laser source includes materials with negative index of refraction dependence on temperature and with temperature independent coincidence between resonator modes and a set of specified frequencies such as DWDM channels in telecommunications applications. The free spectral range may be adjusted to equal a rational fraction of the specified frequency interval. An advantageous embodiment of a tapered waveguide may be used to efficiently couple different size waveguides, such as in a resonator containing both a semiconductor diode amplifier waveguide and a planar waveguide structure for coupling to an optical fiber. An advantageous embodiment of a lensed planar waveguide may be used to efficiently couple to a different size waveguide such as a semiconductor diode amplifier waveguide.
