Monolithic Integration of Waveguide Gratings and Quantum-Well Distributed-Feedback Laser for Implementation of Subminiature Optical-Disc Pickup Head

Abstract

We propose a subminiature optical-disc pickup head implementation by monolithic integration of wave- guide grating components, a graded-index separate-confinement heterostructure single-quantum-well distributed-feedback laser and photodiodes. Fabrication of a prototype device and the results of a preliminary experiment are presented.
