Integrated planar Bragg grating stabilized diode lasers

Summary form only given. Grating stabilized diode lasers exist in many different configurations, typically using bulk and fiber Bragg gratings. In the last couple of years grating stabilized lasers based on a semiconductor gain chips coupled to integrated or planar lightwave circuits containing Bragg gratings have been demonstrated and developed. These devices not only exhibit excellent optical properties such as ultra-low RIN and phase noise, but also compact size and greater opportunities for mass production. We shall present our latest developments of silica planar Bragg grating stabilized diode lasers, and in particular the generation of tunable narrow linewidth sources for gas sensing.
