Multimode Selenide-Chalcogenide Glass Fiber-Based MIR Spontaneous Emission Sources with Shaped Output Spectrum

In this contribution it is shown that broadband emission stretching from 2000 nm up to 6000 nm can be achieved when using selenide-chalcogenide glass. It is also shown experimentally that by appropriate selection of pumping wavelengths the shape of the output spectrum can be varied to suit a particular application.
