Abstract:
1. A device which is composed of: (a) a reflector providing at least one reflectivity stopband, (b) a gain region with means of generating optical gain introduced into at least one layer of said reflector, (c) a gain spectrum of said gain region overlapping with the reflectivity stopband of said reflector, (d) a passive optical cavity attached to said reflector such that a small fraction of the optical field of the passive cavity optical mode penetrates into the gain region placed in the reflector, wherein said passive optical cavity has a resonance wavelength, and wherein a requested temperature dependence of said resonance wavelength of the said optical mode is realized, wherein said requested temperature dependence is selected from the group including wherein each of the possibilities of (i) through (ii) can be realized.
