Abstract :
Summary form only given. Very reliable, high performance monolithic dual visible light emitting GaInP-AlInGaP QW laser diodes are described with 25 μm centre to centre spacing. Record-low crosstalk of less than 3% at T=50°C in the full output power range of 2-20 mW/channel is demonstrated. Crosstalk and droop are related, both theoretically and experimentally, to lasing wavelength, output power and device geometry
