Abstract

Three types of light sources based on superluminescent diodes (SLDs) of NIR ranges 800 – 880 nm and 860 – 950 nm with spatially single mode active channels were studied. Light-emitting modules have demonstrated free space continuous wave (CW) output power of up to 150 mW and 75 mW ex single mode optical fiber (SMF), at spectral bandwidth of about 25 nm. Master Oscillator Power Amplifier (MOPA) system in which SLD of the first type was used as an active element of a power amplifier and blue-shifted SLD as a master oscillator permitted to broaden spectral bandwidth up to 50 nm at the same output optical power level. The estimated lifetime of these devices is more than 10000 hours. High power combined light source based on two MOPA systems with spectral FWHM of more than 100 nm was realized.
