Abstract
An easily fabricated high-power index-guided laser, the inverted channel substrate planar (ICSP) structure, has been developed using the two-step metal-organic chemical vapour deposition (MOCVD) technique. Linear output power characteristics were observed to 30 mW CW on submount with junction side up without facet coatings. The device operated in a stable single mode to a power >25 mW. Improved ICSP lasers with facet coatings demonstrate a stable high output power of 65 mW CW and a differential quantum efficiency of 60%.Keywords
