Analysis of Optical Properties for Square, Circular and Hexagonal Photonic Crystal Fiber

Abstract

This paper presents four rings square, circular, and hexagonal photonic crystal fiber (PCF) geometry for analyzing different optical properties in a wavelength ranging from 800 nm to 1600 nm. These three types of geometry have been used for analyzing Effective area, Propagation constant, Confinement loss and Waveguide dispersion. Silica glass is chosen as background material and the cladding region is made of four air hole layers. COMSOL Multiphysics (v.5) software is used to simulate these proposed PCF geometries. From the numerical analysis, it is found that the effective area is small for hexagonal PCF geometry and large for square PCF geometry (11.827 µm 2 , 10.588 µm 2 and 9.405 µm 2 for square, circular, and hexagonal PCF geometry respectively).From the analysis, the Confinement loss is approximately zero at wavelength ranges from 800 nm to 1250 nm and approximately zero waveguide dispersion is achieved from 900 nm to 1500 nm for all the three PCF structures. Again, negative dispersion approximately −30.354 ps/(nm•km) is achieved for circular PCF structure at the wavelength of 900 nm.

Design and Investigation of a High-Sensitivity PCF Sensor for the Detection of Sulfur Dioxide

“…Because of its ability to control light in hollow bodies, the loss of blockage is very low and the contact of light is increased, resulting in increased fiber sensitivity [2]. A number of reported works [3][4][5][6][7][8][9][10][11][12][13][14][15][16] have been developed to investigate the performance of optical sensors based on PCF. In several applications, PCF is used, such as gas detection [3][4], chemical detection [5][6], pressure detection [7], biomedical and temperature sensing, etc.…”

“…These bio-sensing and chemical senses play an important role in medical science. As a result, most researchers keep an eye on the detection of fluid, chemical, and gas sensitivities [12][13][14][15][16]. Several numbers of research studies on gas detection were reported.…”

Alcohol Sensing through Photonic Crystal Fiber at Different Temperature

“…Where in conventional fibers, designing is not so easy, core size is limited, material selec- tion is tough etc. Moreover, these limitations on the geometry hamper the flexibility in recognizing fiber properties such as dispersion [2] [7], confinement loss [8] [9], birefringence [2] [9], relative sensitivity [10] etc. PCF provides us with long distance light propagation that was not possible previously.…”

“…Light propagation characteristics can be controlled by adjusting the air holes in the core and cladding region. A lot of research studies are already done in the fields of optical communications [10] [11], nonlinear optics [11] and sensing [12] [13] [14].…”
