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 کاملSemi-classical Noise Treatment of Generated Supercontinuum Light by a Finite Energy Airy Pulse
In this paper, a stochastic term is added to the classical generalized nonlinear Schrödinger Equation to describe the noise generated when light pulses propagate in a fiber. It has been shown that the generated supercontinuum light source fluctuates up to 50% of its output temporal intensity profile due to noises of different sources. The simulation method devised has been applied to the propag...
متن کاملMIR supercontinuum in all-normal dispersion Chalcogenide photonic crystal fibers pumped with 2μm femtosecond laser
We demonstrate mid-infrared supercontinuum generation in an all-normal dispersion Chalcogenide PCF pumped by fiber laser. The -20dB bandwidth is 1.7~2.7μm dominated by selfphase modulation and optical wave breaking. Tapering is proposed to improve performance.

متن کاملTruncated thermalization of optical waves through supercontinuum generation in photonic crystal fibers
We revisit the process of optical wave thermalization through supercontinuum generation in photonic crystal fibers. We report theoretically and numerically a phenomenon of ‘truncated thermalization’: The optical wave exhibits an irreversible evolution toward a Rayleigh-Jeans thermodynamic equilibrium state characterized by a compactly supported spectral shape. This phenomenon sheds new light on...
متن کاملRecord power, ultra-broadband supercontinuum source based on highly GeO2 doped silica fiber
We demonstrate highly germania doped fibers for mid-infrared supercontinuum generation. Experiments ensure a highest output power of 1.44 W for a broadest spectrum from 700 nm to 3200 nm and 6.4 W for 800 nm to 2700 nm from these fibers, while being pumped by a broadband Erbium-Ytterbium doped fiber based master oscillator power amplifier. The effect of repetition frequency of pump source and l...
