Optical properties of selectively oxidized vertical cavity laser with depleted optical thyristor structure

Abstract

The authors show that the optical properties of selectively oxidized vertical cavity lasers with a depleted optical thyristor structure have a low threshold current and high sensitivity to input optical light. The oxidized thyristor laser clearly shows a nonlinear s-shaped current-voltage and lasing characteristics. A switching voltage of 5.24 V, a holding voltage of 1.50 V, and a very low threshold current of 0.65 mA are measured, making these devices attractive for optical processing applications.
