Abstract

Due to the demand on accurate metrology applications, the request for stable and powerful semiconductor laser is strongly increasing. An accurate analysis and optimization of the epilayer active material and of complex Bragg grating geometries allows to design and fabricate narrow linewidth DFB lasers without limiting the power output range. This general approach is suitable for laser devices emitting in a wide wavelength range within visible and infrared and based on different material platforms, such as InP, GaAs or GaN. The fabricated devices exhibit linewidth as narrow as few hundreds kHz and power output in the range of few tens mW.
