Abstract

A mask-defined array of multiple-wavelength vertical-cavity surface-emitting lasers with sub-milliamp threshold currents over a 22. nm wavelength span was fabricated with a single epitaxial growth on a conventional substrate. Tuning is achieved by using the combination of lateral and vertical wet oxidn. of an AlGaAs layer inside the cavity. [on SciFinder (R)]
