Paper 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 Psequals1 (mu) W at the wavelength (lambda) sequals1310 nm and a pump power Ppequals 200 mW at the wavelength (lambda) pequals1020 nm. The Fabry-Perot laser, based on the aforesaid buried channel waveguide terminated pump power Pthequals16mW and a slope efficiency Sequals8%.
