Abstract
Optical techniques have a momentous role in different Bio-sensing application, medical diagnosis and treatment. The availability of suitable Bio-materials such as poly lactic acid (PLA), poly acrylic acid (PAA) and ethanol has crucial impact on the designing of Photonic Crystal Fibre (PCF). The device performance and the bio-photonic applications are greatly affected by the different properties of optical, mechanical and biological and functionalities of these bio-materials. Bio-materials results in low optical loss due to its high clearness. It has moderately very less reflection, absorption and scattering of light. The different characteristics of PCF are analysed by using the different polymeric optical bio-materials. Waveguide properties have been numerically investigated by utilising the full vectorial finite element method (FEM). Dispersion at wide range of wavelength may be tuned by changing the structure geometry of bio-materials. Refractive index of Bio-materials influences the properties of Photonic Crystal fibre (PCF). A comparative result of proposed materials PCF characteristics shows highly negative dispersion, low confinement loss.
