Chalcogenide Photonic Crystal Fiber Research Articles

Computational study of 3–5 μm source created by using supercontinuum generation in As_2S_3 chalcogenide fibers with a pump at 2 μm

We present simulation results for supercontinuum generation using As(2)S(3) chalcogenide photonic crystal fibers. We found that more than 25% of input power can be shifted into the region between 3 microm and 5 microm using a pump wavelength of 2 microm with a peak power of 1 kW and an FWHM of 500 fs. The broad dispersion profile and high nonlinearity in As(2)S(3) chalcogenide glass are essential for this application.

Linear and Nonlinear Characterizations of Chalcogenide Photonic Crystal Fibers

In this paper, we investigate the linear and nonlinear properties of GeSbS and AsSe chalcogenide photonic crystal fibers. Through several experimental setups, we have measured the second- and third-order chromatic dispersion, the effective area, losses, birefringence, the nonlinear Kerr coefficient as well as Brillouin and Raman scattering properties.
