Abstract
A vertical cavity surface emitting laser (VCSEL) array is provided. Each tunable VCSEL includes an output coupling mirror; a high reflectivity mirror; an active cavity material structure disposed between the output coupling mirror and the high reflectivity mirror; and a spacer layer disposed between the output coupling mirror and the active cavity material. A tuning cavity is defined within the spacer layer. Each VCSEL further includes a first contact pad and a second contact pad designed to receive a driving voltage; a tuning electrode on a first surface of the output coupling mirror for tuning the emission wavelength to a distinct wavelength.
