At. Semenov et al., SUPERLUMINESCENT DIODES FOR VISIBLE (670 NM) SPECTRAL RANGE BASED ON ALGAINP GAINP HETEROSTRUCTURES WITH TAPERED GROUNDED ABSORBER/, Electronics Letters, 29(6), 1993, pp. 530-532
Visible (670 nm) superluminescent diodes (SLDs) based on AlGaInP/GaInP
heterostructures with tapered grounded absorber have been developed.
The SLDs have CW output power up to 4 mW at 20-degrees-C, spectral ban
dwidth 12 nm and spectral ripple less than 10%.
