Abstract :
A record wide continuous wavelength tuning range of 10.1 μm is demonstrated in vertical-cavity surface-emitting lasers (VCSELs) with monolithically integrated thin-film metal heaters. Single longitudinal mode and single transverse mode are maintained throughout the tuning range. The thin-film heater can stand higher temperatures over a wider tuning range. It is also separated and electrically isolated from the laser, and can be applied to most existing VCSEL structures
