Short wave, a vertical cavity surface emitting laser as and al - free active region

摘要

A short wavelength VCSEL including a mirror stack positioned on a substrate, formed of a plurality of pairs of relatively high and low index of refraction layers a second mirror stack formed of a plurality of pairs of relatively high and low index of refraction layers, an active region sandwiched between the first stack and the second stack, the active region being formed of quantum well layers of GaAsP having barrier layers of GaInP sandwiched therebetween, the quantum well and barrier layers having substantially equal and opposite lattice mismatch.
