✦ Synopsis
The method of spectral selection based on weak coupling between a tilted short Fabry-Perot interferometer and a semiconductor optical amplifier has been proposed. An unusual effect was discovered at a certain inclination. Narrowband spectral maxima are observed in the light backreflected from a tilted short base Fabry-Perot interferometer at natural resonances. To demonstrate possible use of this effect for creation of selective feedback in a laser, a semiconductor laser with wavelength tuning range of ±10 nm at central wavelength 1290 nm and coherence length 8 mm has been developed.
