Abstract

A ring-cavity surface emitting quantum cascade laser (RCSE-QCL) may include a ring-shaped active region having first and second opposing facets. One of the first and second opposing facets may define a radiation emitting facet. The RCSE-QCL may also include a ring-shaped phase shifter aligned with the radiation emitting facet and having a spiraled surface.
