Abstract

Surface emitting semiconductor lasers eliminate the necessity for facet cleaving and allow for wafer scale testing, which increase the manufacturing yield and reduces the cost. However, in the mid-infrared, surface emitting semiconductor lasers are significantly underdeveloped compared to edge emitting devices. The proposed STTR Phase II research is to demonstrate a prototype using ring-cavity surface-emitting quantum cascade laser (QCL) array for power scaling at a wavelength of 4.5 microns. This approach allows for two-dimensional integration of multiple emitters on a single chip. A single mode emitting spectrum, excellent beam quality, and high power can be simultaneously achieved with this technology. The proposed high power mid-infrared laser sources are highly attractive for standoff spectroscopy, free-space communication and infrared countermeasure systems, in which cost, size, and weight are prime factors. Upon completion of the project, an inexpensive, compact, and lightweight mid-infrared laser source will be available for a much broader range of applications.
