Abstract
Laser diodes with highly strained InGaAs quantum wells, emitting at , embedded in a GaAs waveguide were investigated. This Letter reviews the design of the vertical structure for enclosing high output power in angles smaller than 18°. Example designs were processed to stripe-width lasers with an optical cavity. When these are mounted on C mounts, they give an output power of under quasi-cw operation from a single emitter.
