Abstract :
High-power operation (35 mW/spl times/2) at 70/spl deg/C in a 680 nm band individually addressable AlGaInP/GaInP 2-beam laser diode has been demonstrated for the first time. The 2-beam laser diode employs V-grooves for electrode separation and reduction of laser capacitance, and accurate junction-down bonding to silicon carbide (SiC) submount. Therefore, simultaneous high-power operation, high frequency response and high reliability are achieved.<>
