We report on green (550–560 nm) electroluminescence (EL) from (Al0.5Ga0.5)0.5In0.5P–(Al0.8Ga0.2)0.5In0.5P double p–i–n heterostructures with monolayer–scale tensile strained GaP insertions in the cladding layers and light–emitting diodes

Morphology evolution in (In,Ga)As-Ga(As,P) strain-compensated multilayer structures is studied. The effects of nanoscale interface corrugation and phase separation are evident after the third period of the multilayer structure and become more pronoun

We report on 980nm InGaAs∕AlGaAs lasers with a broad waveguide based on a longitudinal photonic band crystal concept. The beam divergence measured as full width at half maximum was as narrow as 15W pulsed operation as limited by the current source.

We studied wavelength stabilized all-epitaxial 970nm spectral range GaAs∕GaAlAs tilted cavity lasers (TCLs). Single transverse mode edge-emitting 4-μm-wide ridge lasers demonstrated spatial and spectral single mode continuous wave operation with a

The authors study 850nm GaAs∕AlGaAs longitudinal photonic band crystal lasers with a vertical far field divergence of 9° (full width at half maximum). Differential quantum efficiency of 95% is achieved at a cavity length of 500μm. A total optical

Narrow ridge lasers of 1.5μm range based on InAs∕InGaAs quantum dots grown on metamorphic (In,Ga,Al)As layers deposited on GaAs substrates using defect reduction technique are studied. It is shown that the lasers operate continuous wave (cw) in a
