Novel Dispersion Properties of Photonic Crystal Fiber

Abstract

Photonic crystal fibers (PCFs), which are also called microstructured fibers or holey fibers possess a core area surrounded by a cladding region composed of a fine array of micrometer-sized air holes that extend along the full fiber length. The wavelengthscale features in PCFs lead to novel properties including endlessly single-mode guidance, flexible dispersion control, and ultra-high nonlinearity. In this paper, novel dispersion properties of photonic crystal fiber, which are not easily achievable with conventional step-index structured fiber are reviewed. Furthermore, new possibilities in the area of soft glass based highly nonlinear fibers provided by the PCF technology are also presented.

Generation of stable two-color laser pulses in photonic crystal fiber for microscopy

“…14) The conversion efficiency also can be enhanced with highly nonlinear PCF based on soft glass. 22) At present, the pump power cannot be increased in this spectral range because of the type of the pump laser source being used. In order to get higher pump power, we have changed the central wavelength of pump pulse from 840 to 800 nm by adjusting the insertion of the second prism.…”
