High-power laser diodes (LDs) are strongly demanded as a light source of display applications. In this work, the reliability of a high-power 638 nm broad stripe (BS) LD was studied from the viewpoint of not only gradual degradation but also catastrop

Reliabilities of the 638-nm triple emitter broad area laser diode (BA-LD) with the window-mirror structure were studied. Methodology to estimate mean time to failure (MTTF) due to catastrophic optical mirror degradation (COMD) in reasonable aging dur

Zinc (Zn) diffusion through MOCVD-fabricated InP and InGaAsP layers, and the corresponding Zn doping profile at the heterojunction interface were studied as part of the doping profile control for laser diodes. It was found that the Zn doping profile

Laser based displays, such as 10 lm to 70K lm laser projectors and laser diode (LD) backlight liquid crystal display (LCD) TVs, have attracted much attention because of the large gamut, low power consumption, and so on. Laser light sources for the di

The mechanism of passivation effect on the hole concentration in Zn-doped (Al 0.7 Ga 0.3 ) 0.5 In 0.5 P layers grown by metalorganic chemical vapor deposition (MOCVD) is investigated. It is found that oxygen concentration in AlGaInP should be suppres

We introduced a multiple quantum barrier (MQB) which was grown by MOCVD between the active layer and p-cladding layer to enhance potential barrier height. The MOCVD system was improved to realize the growth of MQB structures for the first time. We co
