Strain-induced effects have been expected to improve laser diode characteristics. In this paper, we report both compressive and tensile strain effects on the performance of AlGaInP/GaInP visible lasers, which have attracted much attention as light sources in optical information processing systems. An extremely low threshold current density was obtained for a compressive strained device, and TM mode lasing was observed for a tensile strained device.
