Abstract
Laser diode/cylindrical microlens assembly including a crossed-pair of passively aligned cylindrical microlenses attached to a substrate on which is mounted a laser diode chip. The microlenses are mounted in an 'aplanatic' configuration with their flat surfaces facing the emitting facet of the diode, which arrangement provides for passive alignment and possible automated mounting, but requires no additional lenses for astigmatism correction. The crossed pair of lenses can collimate or focus the laser diode beam, for example focusing into a single mode fiber.
