Paper Abstract

A promising approach for efficient microlenses and compact diode laser systems is reviewed. Development of one-step etching of the lens preform and effective wafer protection in mass transport has led to a considerably simplified process and increased reproducibility. Anamorphic microlenses have been fabricated and demonstrate capability for simple compact optics for tapered high-power diode lasers, with coupling of 347 mW into a single-mode fiber. GaAs microlenses have been developed as a first step toward monolithic laser/lens integration. Simple hybrid integration has been demonstrated with a direct mounting of microlenses on packaged lasers.
