In gas detection systems based on a single absorption line, wide-range, precision-tunable, continuous-wave laser sources are desired in order to allow for accurate targeting and measuring absorption profiles of particular gas species. A widely tunable ring laser using an intra-cavity wavelength tuning mechanism based on asymmetric Mach-Zehnder interferometers has been realized in the form of a monolithic indium phosphide photonic integrated circuit following a generic photonic integration approach. Furthermore, such integration technology enables the possibility of a co-integration of multiple lasers on a single photonic chip and allowing a gas detection system to monitor a few gas species simultaneously.
