Co-doped Dy3+ and Pr3+ Ga5Ge20Sb10S65 fibers for mid-infrared broad emission

Abstract : Rare earth ion doped materials are means to obtain cost-effective infrared light sources, with enough brilliance for applications such as gas sensing. Within a sulfide matrix, the simultaneous luminescence of both Pr3+ and Dy3+ in the Ga(5)Ge(20)Sb(10)S(65 )glass is reported. The use of these two rare earths is giving rise to a broad continuous luminescence in the 2.2-5.5 mu m wavelength range, which could be used as a mid-infrared light source for gas-sensing applications. The demonstration of CO2 and CH4 detection using a fiber drawn from these materials is reported. (C) 2018 Optical Society of America
