Computational study of 3–5 μm source created by using supercontinuum generation in As2S3 chalcogenide fibers with a pump at 2 μm

چکیده
We present simulation results for supercontinuum generation using As2S3 chalcogenide photonic crystal fibers. We found that more than 25% of input power can be shifted into the region between 3 μm and 5 μm using a pump wavelength of 2 μm with a peak power of 1 kW and an FWHM of 500 fs. The broad dispersion profile and high nonlinearity in As2S3 chalcogenide glass are essential for this application. © 2010 Optical Society of America OCIS codes: 060.2280, 060.2390, 320.6629.

Mid-infrared supercontinuum generation using dispersion-engineered Ge(11.5)As(24)Se(64.5) chalcogenide channel waveguide.
We numerically investigate mid-infrared supercontinuum (SC) generation in dispersion-engineered, air-clad, Ge(11.5)As(24)Se(64.5) chalcogenide-glass channel waveguides employing two different materials, Ge(11.5)As(24)Se(64.5) or MgF(2) glass for their lower cladding. We study the effect of waveguide parameters on the bandwidth of the SC at the output of 1-cm-long waveguide. Our results show tha...
متن کاملMid-infrared supercontinuum generation in a suspended-core As2S3 chalcogenide microstructured optical fiber.
We demonstrate the supercontinuum (SC) generation in a suspended-core As(2)S(3) chalcogenide microstructured optical fiber (MOF). The variation of SC is investigated by changing the fiber length, pump peak power and pump wavelength. In the case of long fibers (20 and 40 cm), the SC ranges are discontinuous and stop at the wavelengths shorter than 3500 nm, due to the absorption of fiber. In the ...

Wepresent the results of an investigation of the nonlinear characteristics of a new class of robust,multimaterial, allsolid chalcogenide nanotapers prepared from high-index-contrast chalcogenide fibers. The fiber is drawn from a preform produced bymultimaterial coextrusion and consists of chalcogenide core and cladding (which dictate the optical properties) and a built-in thermally compatible p...
متن کاملA mid-IR source with increased bandwidth using tapered As2S3 chalcogenide photonic crystal fibers
We present simulation results for supercontinuum generation using tapered As2S3 chalcogenide photonic crystal fibers (PCFs). We demonstrate that an increased soliton self-frequency shift can be achieved using a tapered PCF. There is an optimal tapered PCF, which yields an additional 0:4 mm shift to longer wavelengths relative to the shift that is obtained in an untapered PCF, leading to an incr...
متن کاملIncreased mid-infrared supercontinuum bandwidth and average power by tapering large-mode-area chalcogenide photonic crystal fibers.
The trade-off between the spectral bandwidth and average output power from chalcogenide fiber-based mid-infrared supercontinuum sources is one of the major challenges towards practical application of the technology. In this paper we address this challenge through tapering of large-mode-area chalcogenide photonic crystal fibers. Compared to previously reported step-index fiber tapers the photoni...
