A theoretical investigation of the feasibility of planar channel waveguide amplifiers and Fabry-Pérot lasers, made of praseodymium (Pr³⁺)-doped chalcogenide glass, is performed by means of a homemade computer code. The buried channel waveguide amplifier, having both the core and the substrate doped with a Pr³⁺ concentration N = 3000 ppm, shows a gain close to G = 7 dB for an input signal power of P_s = 1 μW at the wavelength λ_s = 1310 nm and a pump power of P_p = 200 mW at the wavelength λ_p = 1020 nm. The Fabry-Pérot laser employing this buried channel waveguide, terminated by an input mirror having reflectivity R₁ = 98% and an output mirror having reflectivity R₂ = 41%, exhibits a threshold pump power P_th = 16 mW and a slope efficiency S = 8%.
