Abstract
Perfonnance 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 t11ese 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.
