چکیده
We demonstrate the first all-chalcogenide ring fiber laser as well all chalcogenide Brillouin laser. The compact device is made from combination of an As2Se3 optical coupler for insertion pump light and extraction light, As2S3 nonlinear gain to ensure oscillation. Thanks strong As2S3, only 3m amplifying required reach threshold, thus making a resonant cavity with free spectral range significantly larger than spectrum. therefore naturally enables single longitudinal mode operation without additional filtering device. Acting coherence enhancing component, resulting proof concept benefits linewidth reduction factor 7 respect

All-solid all-chalcogenide microstructured optical fiber.
The realization of an all-solid microstructured optical fiber based on chalcogenide glasses was achieved. The fiber presents As(2)S(3) inclusions selected as low refractive index material (n = 2.4) embedded in a As(38)Se(62) glass matrix (n = 2.8). The single mode regime of the fiber was demonstrated both theoretically by multipole method calculations and experimentally by near field measuremen...
متن کاملOptimization of Bistability in Nonlinear Chalcogenide Fiber Bragg Grating for All Optical Switch and Memory Applications
We solve the coupled mode equations governing the chalcogenide nonlinear fiber Bragg gratings (FBGs) numerically, and obtain the bistability characteristics. The characteristics of the chalcogenide nonlinear FBGs such as: switching threshold intensity, bistability interval and on-off switching ratio are studied. The effects of FBG length and its third order nonlinear refractive index on FBG cha...

متن کاملMode-locked fiber laser based on chalcogenide microwires.
We report the first mode-locked fiber laser using a chalcogenide microwire as the nonlinear medium. The laser is passively mode-locked with nonlinear polarization rotation and can be adjusted for the emission of solitons or noise-like pulses. The use of the microwire leads to a mode-locking threshold at the microwatt level and shortens the cavity length by 4 orders of magnitude with respect to ...
