title = "Demonstration of all optical logic gates by single/differential typed vertical cavity laser with depleted optical thyristor",
abstract = "Latching optical switches and optical logic gates with AND or OR, plus the INVERT functionality are demonstrated for the first time by the monolithic integration of a single and differential typed vertical cavity lasers with depleted optical thyristor (VCL-DOT) structure with a low threshold current of 0.65 mA, a high on/off contrast ratio of more than 50 dB, a high slope efficiency of 0.38 mW/mA, and high sensitivity to input optical light. By simply changing a reference switching voltage, this single-typed device operates as two logic functions, optical logic AND and OR. The differential-typed VCL-DOTs operate also as all logic gates, AND/NAND, OR/NOR, and INVERT function by simple change of a reference input light power. The thyristor laser fabricated by using the oxidation process shows a high optical output power efficiency and a high sensitivity to the optical input light.",
