Abstract

The feasibility of a planar channel waveguide amplifier and laser made of praseodymium (Pr³⁺) doped chalcogenide glass, based on the binary composition GeS₂, is investigated by means of an appositely implemented computer code. The buried channel waveguide amplifier, having both core and substrate doped with a dopant concentration Nequals3000 ppm, shows gain close to Gequals7 dB for an input signal power of P_sequals1 (mu) W at the wavelength (lambda) _sequals1310 nm and a pump power P_pequals 200 mW at the wavelength (lambda) _pequals1020 nm. The Fabry-Perot laser, based on the aforesaid buried channel waveguide terminated pump power P_thequals16mW and a slope efficiency Sequals8%.
