Abstract
Multi-surface emitting mid-IR multiwavelength distributed-feedback quantum cascade ring lasers laid out in a concentric circle are disclosed. The lasers utilize quantum cascade core designs to produce optical gain in the mid-infrared region and may generate several wavelengths simultaneously or sequentially. Methods of making along with methods of using such devices are also disclosed.
