Superbroadband high-power superluminescent diode emitting at 920 nm

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.

“…The SLD samples had a standard design described in details in [5]. The axis of the active channel of 4.0 µm width was tilted at 7° angle to the normal to crystal facets.…”

“…It is well known that SLDs (SOAs) based on quantum-well heterostructures may exhibit significantly wider ASE spectrum [6][7][8] . It is obvious that using SLD and SOA based on the appropriate heterostructures it is possible to obtain in the same design much broader spectrum (lower coherence) of the output emission.…”

It is experimentally shown that a semiconductor optical amplifier (SOA) ensures a significant improvement of output characteristics of a superluminescent diode (SLD). Using SOA based on (InGa)PAs SC DH (central wavelength -1300 nm) in MOPA system with SLD as a master oscillator a CW output power of 50 mw ex SM fiber was obtained. The same SOA used as a combiner of its own ASE and red-shifted input SLD light signal permits obtaining the output emission with linewidth near 70 nm.

“…SLDs of Type I and Type II used in 'BroadLighter-890' were previously investigated and described in [5,6]. The spectra of these devices at working regimes suitable for combining their emission are shown on Fig.…”
