Degenerate Distributed Feedback Lasers

Abstract

Degenerate distributed feedback lasers utilizing DBE-supporting waveguides are provided. In one embodiments, a degenerate distributed feedback laser (DDFB) is provided, the DDFB laser comprising: a pump source operatively connected to a gain system, wherein the pump source provides power to a gain system; the gain system operatively connected to at least one DBE-supporting waveguide, wherein the gain system stimulates emission and amplification for lasing; at least one DBE-supporting waveguide that supports four degenerate modes and a degenerated feedback; and a coupler operatively connected to the at least one DBE-supporting waveguide, wherein the coupler collects and focuses light from the DBE-supporting waveguide and outputs a laser beam.
