An exploration of slab-coupled semiconductor lasers

To obtain a high-power and efficient single-mode laser, a new laser called the slab coupled optical waveguide laser （SCOWL） has been developed. We have simulated its structure and grown the chip with this structure by low-pressure metal organic chemical vapor deposition. We have also produced the broad-area SCOWL and compared it with the traditional structure laser in terms of some performances. This work lays the foundation for further research of ridged lasers with the same structure.
