Paper Abstract

High-power (greater than 50 mW) and high-temperature (greater than 70 degrees Celsius) operation of 650 nm-band AlGaInP lasers are required as light sources for high-density and recordable optical disk memory systems. However, there remains the problems such as small band-offset in the conduction band and facet degradation in AlGaInP material system which limit the high-power and high-temperature operation. This paper presents new techniques in order to achieve such high performance lasers: Window-mirror structure and real index guided structure.
