Abstract

Performance characteristics of recently developed superluminescent diodes (SLDs) based on double quantum-well (InGa)As heterostructure and InAs/AlGaAs/GaAs quantum-dot heterostructure are presented. Emission spectra of these SLDs cover spectral bands 960-1080 nm and 1100-1230 nm respectively. Owing to their usage, combined light sources of BroadLighter series cover now the entire NIR-range of 770-1230 nm. New prototypes of swept-wavelength light sources in the range of 820-1080 nm based on quantum-well broadband SOAs and tunable acousto-optic filters are described.
