Abstract

We present a theoretical investigation of a novel type of distributed-feedback high-power diode laser with a "curved-groove" diffraction grating (c-DFB), which is predicted to give enhanced spectral and spatial output characteristics. Analyzed spectral properties of the proposed device are found to be identical to the conventional DFB laser of the same length and coupling. It has been also shown that the lateral optical modes of the proposed c-DFB laser are the cylindrical symmetry, which implies that the power generated by such a device can be brought to a common focus.
