Abstract: In this paper, a Silicon nanowire embedded pentagonal Photonic Crystal Fibre (PCF) based Broadband Light Source is proposed as a potential candidate for the Optical Communication systems. The dispersion and nonlinearity characteristics of the PCF are analyzed by the Finite Element Method. The propagation of the Secant Hyperbolic pulse through the proposed PCF is studied by numerically solving the Nonlinear Schrödinger Equation using Split-Step Fourier Method. A Soliton pulse of 25 W peak power and duration of 50 fs at 1550 nm is used for the generation of a broadband light signal.

TL;DR: It is demonstrated analytically and numerically that a subwavelength-core dielectric photonic nanowire embedded in a properly designed photonic crystal fiber cladding shows evidence of a previously unknown kind of nonlinearity which acts on solitons so as to considerably reduce their Raman self-frequency shift.
Abstract: We demonstrate analytically and numerically that a subwavelength-core dielectric photonic nanowire embedded in a properly designed photonic crystal fiber cladding shows evidence of a previously unknown kind of nonlinearity (the magnitude of which is strongly dependent on the waveguide parameters) which acts on solitons so as to considerably reduce their Raman self-frequency shift. An explanation of the phenomenon in terms of indirect pulse negative chirping and broadening is given by using the moment method. Our conclusions are supported by detailed numerical simulations.

TL;DR: When its diameter goes close to or below the wavelength of the guided light, an optical microfiber/nanofiber exhibits favorable properties such as tight optical confinement, strong near-field interaction, and excellent mechanical strength, which offers plenty of choices for combining a variety of functionalized materials ranging from semiconductors and metals to laser dyes as discussed by the authors.

TL;DR: In this paper, a spiral silica photonic crystal fiber (SSPCF) is proposed for supercontinuum generation in the visible region, which shows high nonlinearity parameter (1433W -1 km -1 ), high Raman gain (698.478W −1 km −1 ), ultraflattened dispersion (-0.05064 ps/nm 2.00161 dB/km) at 600 nm.
Abstract: A dispersion flattened, spiral silica photonic crystal fiber (SSPCF) is presented here for supercontinuum generation in the visible region. Two zero dispersion wavelengths (ZDWs) (570nm & 630nm) are obtained in the visible region for a core diameter of 600nm and the range of the anomalous dispersion increasing with the increment of the core diameter. The fiber shows high nonlinearity parameter (1433W -1 km -1 ), high Raman gain (698.478W -1 km -1 ), ultraflattened dispersion (-0.05064 ps/nm 2. km) and very low confinement loss (0.00161 dB/km) at 600 nm. The proposed SSPCF shows improvement over the dispersion control of a hexagonal PCF, and low damage threshold of a highly nonlinear (HN) soft glass PCF. So it can be an excellent candidate for generating supercontinuum in the visible region with HeNe laser of pump wavelenght at 612nm. Full Text: PDF References: J. K. Ranka, R. S. Windeler, and A. J.

TL;DR: In this article, a silica spiral photonic crystal fiber is presented for tailoring two zero dispersion wavelengths (ZDWs) in the visible region, which has two ZDWs (523.1 and 716.8 nm) along with a very high nonlinearity parameter (1060 W−1 km−1 at 500 nm).
Abstract: A silica spiral photonic crystal fiber is presented here for tailoring two zero dispersion wavelengths (ZDWs) in the visible region. The proposed fiber has two ZDWs (523.1 and 716.8 nm) along with a very high nonlinearity parameter (1060 W−1 km−1 at 500 nm) around the visible region. The proposed design shows improvement over the group dispersion control and air holes collapsibility of highly air filled hexagonal photonic crystal fiber (HPCF), and low damage threshold of the soft glass photonic crystal fiber. Besides, the low air filling fraction (≈43%) of the proposed design reduces the probability of sustaining higher order modes in the fiber and also ensures easy fabrication due to fewer air holes.
