标题(英语)

Slow light edge-emitting laser of photonic crystal chirp waveguide


摘要(英语)

The invention discloses a slow light edge-emitting laser of photonic crystal chirp waveguide, which consists of an air hole type photonic crystal structure manufactured on a semiconductor chip. The structure is divided into three parts, wherein the left part has a slow light waveguide structure and is used for generating laser; the right end has an output waveguide structure, and the diameters of two adjacent rows of air holes inside the output waveguide structure are slightly smaller than the diameters of air holes of peripheral photonic crystals; and a chirp waveguide structure is formed between the slow light waveguide structure and the output waveguide structure, and the diameters of two adjacent rows of air holes inside the chirp waveguide structure gradually reduce from the same size as those of the air holes of the slow light waveguide structure to the same size as those of the diameters of the air holes of the output waveguide structure. The edge-emitting laser provided by the invention adopts a band edge slow-light mode of the photonic crystal chirp waveguide, breaks through the bottleneck that the volume of a defective cavity mode is limited, and uses the chirp waveguide structure to efficiently convert the slow light mode into a normal group velocity waveguide module so as to greatly improve the output efficiency of the edge-emitting laser.
