Abstract

Superluminescent diodes (SLDs) of spectral range 730 – 790 nm with strained single quantum-well (SQW) active layer and spatially single mode ridge waveguide were studied experimentally. SLDs with short active channels < 1000 μm have demonstrated broadband emission spectrum with median wavelength near 765 nm, FWHM of up to 60 nm and free space CW output power in the range 2 – 15 mW at 25°C. SLDs with longer active channels have demonstrated output of up to 150 mW and spectral half-width in the range 40 – 20 nm. TM mode was dominant in output emission.
