Abstract:
Optical sensors found to have many advantages over other conventional sensors. Among these, fiber optic sensors also called as optical fiber sensors use optical fiber and sensing elements to sense physical quantities like temperature, pressure, vibrations, displacements, rotations or concentration of chemical species. Fibers have so many uses in the field of remote sensing because they require no electrical power at the remote location and they have tiny size. Fiber optic sensors are supreme for insensitive conditions, including noise, high vibration, and hot, wet and unstable environments. These sensors can easily fit in small areas and can be positioned correctly wherever flexible fibers are needed. In our studies we use a new class of optical fiber called photonic crystal fiber for sensing application. In this work we design the fiber at first with desired geometry and material. Then we study the optical properties of the designed fiber for sensing application. The participant will get a clear idea about optical fibers working, characteristics and sensing mechanism along with achievement of skill required to design optical fiber and calculate different fiber properties like confinement loss, dispersion, nonlinearity coefficient etc.

Abstract:
A layer of dielectric materials deposited as a film can reflect up to 99.999% of light incident on it for a range of wavelengths. The range can be controlled by designing layer of materials with various thickness and size.
The aim of this project is to optimize and design the all dielectric metasurfaces for achieving perfect reflection at visible wavelengths.
