Abstract :
Strained (Al)GaInP quantum-well ridge lasers with AlGaAs cladding layers have been fabricated on a 5 degrees -off oriented GaAs substrate. Owing to a heat spreading layer, the devices can be operated junction-side up with a CW threshold current of 13 mA. Singlemode operation is achieved up to power levels of 15 mW for devices with uncoated facets.
