title: Raman lasing in a chalcogenide microwire-based Fabry-Perot cavity.
abstract: We propose and demonstrate an all-chalcogenide microwire Raman laser, the first to our knowledge. The gain medium is provided by the Raman effect in a chalcogenide microwire and two Fabry-Perot resonant media are tested for lasing: (1) a cavity made out of a Fresnel reflection at one end of the microwire and a silver coated, broadband mirror at the other end, and (2) a cavity made out of Fresnel reflections at both ends of the microwire. The microwires are pumped in the C-band, and the resulting Raman lasers operate in the L-band. Such an all-chalcogenide microwire laser has the potential to operate over the entire transmission window of chalcogenide glasses, i.e., in the wavelength range of 1.5-10 μm.
