A novel high sensing circular and elliptical PCF are proposed based on selective glass material incorporation in the cladding region. By improving the structural parameter such as cladding diameter, pitch, core diameter, semi-major and semi-minor distance, angle of inclination, and eccentricity on the polarisation characteristics are fully discussed. A full vectorially 2D FDTD method with PML as boundary condition is applied and investigating guiding properties of proposed PCFs. Numerical simulations reveals that the proposed PCFs strongly effect on sensing response at a wavelength equal and greater than 1.55 µm. Additionally Confinement loss, mode field area and numerical apertures are significantly correlated to enhancing sensing arena. The results indicates that elliptical PCF has more sensing response over circular one at a wavelength equal to or greater than 1.55 µm, which is better than other reported literatures. Owing to above mentioned characteristics the proposed novel elliptical PCF can be widely applied in optical communication arena.
