Abstract

General requirements of AlGaInP/InGaP laser diode (LD) for digital versatile disk (DVD) optical pick-up head application, such as wavelength, output power, astigmatism, mode profile, and relative intensity noise (RIN) will be discussed in this paper. Several efforts which have been made to develop AlGaInP/InGaP laser diodes suitable for DVD application will be reviewed. To record or erase signals in a DVD system, an output power of about 30 mW from AlGaInP/InGaP laser diode is required. Several methods which were proposed to increase catastrophic optical damage (COD) level will also be reviewed. A low-power 650-nm-band AlGaInP/InGaP laser diode utilizing double-channel ridge waveguide (DC-RW) structure has been developed at OES/ITRI. Good characteristics of this laser diode such as very low operation current, small astigmatism, and stable fundamental transverse mode operation at a power level of more than 10 mW were obtained. A hybrid optical pick-up head utilizing this laser diode was incorporated in a commercial DVD-video player and functioned with a very good quality.
