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 research will investigate the feasibility of using ring-cavity surface-emitting quantum cascade lasers for power scaling at a wavelength of 4.5 & #181;m. 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.
