Abstract

Photonic crystal fibers (PCF) are more versatile, intriguing and promising than conventional optical fiber. PCFs are divided into two different kinds, the index-guiding PCF and the photonic band-gap (PBG) effect PCF. In conventional index-guiding PCF, there is a lattice of air holes in the silica background, which surround the core. Light in this fiber is guided through the high index solid silica core by total internal reflection mechanism. Fundamentally different from all high index core conventional photonic crystal fiber, in this paper, we propose a new type of Photonic Crystal Fiber (PCF) structure; where instead of using the air-holes in the cladding region, we use boron doped solid silica rods in order to reduce the problems associated with deformities of air-holes in the fabrication of PCF. Also, we analyze few of the properties of the proposed photonic crystal fiber structure such as Endlessly Single Mode(ESM) property and tunable dispersion, and compared with conventional photonic crystal fiber.

Abstract

A photonic crystal fiber (PCF) presents a new way to guide light. The air holes in the fiber work as a cladding, but provide much more flexibility in the design. In this work, the plane-wave expansion technique for generating and analyzing photonic band structures is used. The simple 2D XY array with a hexagonal cross-sectional pattern of air holes in a silicon fiber is analysed for calculating parameters such as mode effective index, dispersion and single mode operation over wide wavelength range. The results of a design sample presented in this article, showing the better result to analyze this new class of fiber. This fiber can be used for biomedical application, spectroscopy, and super continuum generation.
