Paper Abstract

A compact optical head for CD-ROM drives, integrated with a laser diode chip, a photodiode chip, and a holographic optical element in a small optical module, using hybrid assembly technique, has been developed. The module size is 7.5 mm (W) X 8 mm (D) X 3 mm (H), and its weight is 0.6 g. The validity of this optical head design has been demonstrated by successful readout operation for a compact disc.
