| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have successfully fabricated 650-nm band single lateral-mode high-power laser diodes (LDs) by using the 4-inch full-wafer process technology. We realized the high throughput LD production with high-power and reliable performances. The LD characteristics show excellent uniformity over a 88mm diameter area of the 4-inch wafer, e.g. (standard deviation/average) = ±2.3 % for Ith, and ±1.1 % for slope efficiency. The output power more than 350 mW had been obtained with stable lateral mode operation under the operation current 600 mA even at the high temperature 80 ℃. In addition, the operation voltage had been suppressed around 3.0 V even at high power operation by optimizing the ridge formation process and reducing the series resistance. These results confer the promising way to realize the high-speed (over 8×) dual layer recordable DVD systems. | |
