Lasing Characteristics of Very Narrow Planar Stripe Lasers

概要
- 論文の詳細を見る
Lasing characteristics were investigated on the newly developed very narrow planar stripe lasers. The linearity in the light output vs. current curve is remarkably improved and the critical power at which the kink appears exceeds 70 mW from the facet of the laser when the stripe width w is 2.3 μm. The relaxation oscillation in the pulsed light output becomes less pronounced as w is decreased and disappears when w is less than 2.5 μm. The fundamental transverse-mode is stably excited, but the far-field radiation pattern is rather broad and, at high current, two peaks appear in the pattern owing to the very narrow gain-guidance.
