Paper Abstract

We report the demonstration of a fully micro-fabricated vertical-external-cavity surface-emitting laser (VECSEL) operating at wavelengths near 850 nm. The external-cavity length is on the order of 25 microns, and the external mirror is a dielectric distributed Bragg reflector with a radius of curvature of 130 microns that is micro-fabricated on top of the active semiconductor portion of the device. The additional cavity length, relative to a VCSEL, enables higher output power and narrower laser linewidth, and micro-fabrication of the external mirror preserves the manufacturing cost advantages of parallel lithographic alignment.
