| titleOfInvention | Single-longitudinal-mode edge-emitting laser with side grating oxidation-confinement structure, and preparation method therefor |
| abstract | A single-longitudinal-mode edge-emitting laser with a side grating oxidation-confinement structure, and a preparation method therefor. The single-longitudinal-mode edge-emitting laser with a side grating oxidation-confinement structure comprises an N-electrode layer; a substrate (8) arranged on the N-electrode layer; a lower cover layer (7) arranged on the substrate (8); a lower waveguide layer (6) arranged on the lower cover layer (7); an active region (5) arranged on the lower waveguide layer (6); and a ridge strip structure arranged on the active region (5). The ridge strip structure comprises: an upper waveguide layer (4) arranged on the active region (5); an intermediate high-aluminum component layer (3) arranged on the upper waveguide layer (4); an upper cover layer (2) arranged on the intermediate high-aluminum component layer (3); a contact layer (1) arranged on the upper cover layer (2); and a P-electrode layer (9) arranged on the contact layer (1); and a side grating structure that is arranged on a side portion of the ridge strip structure and is of a groove-shaped periodic structure. The present invention facilitates the realization of efficient current injection and a large-mode-volume fundamental transverse mode, and the selection of a grating in a low-loss mode. |
