Supercontinuum Generation in a Highly Nonlinear Chalcogenide/ MgF2 Hybrid Photonic Crystal Fiber
In this paper, we report the numerical analysis of a photonic crystal fiber (PCF) for generating an efficient supercontinuum medium. For our computational studies, the core of the proposed structure is made up of As2Se3 and the cladding structure consists of an inner ring of holes made up As2Se3 and four outer rings of air holes in MgF2. The proposed structure provides excellent nonlinear coeff...
متن کاملSupercontinuum generation in photonic crystal fiber
A topical review of numerical and experimental studies of supercontinuum generation in photonic crystal fiber is presented over the full range of experimentally reported parameters, from the femtosecond to the continuous-wave regime. Results from numerical simulations are used to discuss the temporal and spectral characteristics of the supercontinuum, and to interpret the physics of the underly...
متن کاملDeep-Ultraviolet to Mid-Infrared Supercontinuum in Single-Ring Hollow-Core Photonic Crystal Fiber
We report the first supercontinuum generated in a gas-filled single-ring hollow-core PCF. When pumped with ultrashort pulses at 1500 nm, the emitted spectrum spans three octaves from the deep ultraviolet to the mid-infrared. OCIS codes: (060.0060) Fiber optics and optical communications; (190.0190) Nonlinear optics (320.0320) Ultrafast optics
متن کاملSupercontinuum generation with picosecond ultraviolet pulses in a solid-core photonic crystal fiber
Black light supercontinuum generation is demonstrated as a result of picosecond pumping a solid-core photonic crystal fiber at 355~nm through the combined effects of intermodal four-wave mixing and cascaded Raman scattering. OCIS codes: 190.4370, 190.5650, 190.4005. The study of supercontinuum (SC) generation in photonic crystal fibers (PCF) continues to be an area of active research, motivated...
متن کاملHollow core photonic crystal fiber as a reusable Raman biosensor.
We report that a single hollow core photonic crystal fiber (HC-PCF) can be used for repetitive characterization of multiple samples by Raman spectroscopy. This was achieved by integrating the HC-PCF to a differential pressure system that allowed effective filling, draining and re-filling of samples into a HC-PCF under identical optical conditions. Consequently, high-quality and reliable spectra...
