Abstract

Within the past year significant advances in the development of high-performance vertical-cavity surface-emitting laser (VCSELs) and quantum-well modulators has been achieved. Large arrays of VCSELs with submilliamp thresholds and diffraction limited beams have been produced by MBE growth of InGaAs/GaAs strained-layer quantum-well active regions encompassed by integral AlAs/GaAs quarter-wave stack mirrors. Also, using similar technology, asymmetric transverse Fabry-Perot modulators with transfer efficiencies about 20 percent/V and high-extinction on/off modulation with voltage swing of only 2 volts have been demonstrated. Using superlattice active regions, room-temperature blue shifted absorption modulators have been produced, and self-electrooptic effect devices with record on/off ratios (more than 100:1) have been achieved.
