Monolithic Dual-Wavelength Lasers for CD-R/ DVD+-RW/R/ RAM

摘要

We have succeeded the monolithic integration of a 160 mW GaInP-based laser for DVD+-RW/R/RAM and a 240 mW AlGaAs-based laser for CD-R. DVD high-power lasers had stable 500 hours operation of 160 mW pulsed output power (pulse width: 50 ns, duty cycle: 50%) at 70℃, and CD-R lasers had reliable lifetime of 240 mW at 75℃.
