Broadband radiation sources based on quantum-well superluminescent diodes emitting at 1550 nm

The emission spectra of superluminescent diodes (SLDs) based on a multilayer quantum-well (InGa)PAs heterostructure are studied in the wavelength range from 1450 to 1650 nm. The FWHM of these spectra exceeds 120 nm in certain operating regimes. The experimental samples of light-emitting modules with...

Description
Summary:The emission spectra of superluminescent diodes (SLDs) based on a multilayer quantum-well (InGa)PAs heterostructure are studied in the wavelength range from 1450 to 1650 nm. The FWHM of these spectra exceeds 120 nm in certain operating regimes. The experimental samples of light-emitting modules with output single-mode fibres are fabricated based on the SLDs studied, which produce the output power spectral density above -45 dBm nm{sup -1} within the band over 200 nm. The spectrum of such an emitter covers the main bands (S, C, and L) of WDM telecommunication systems. The possibilities of a further broadening and flattening of the emission band of these SLDs are considered. (lasers)
