Polarization Fiber Optic Sensor Circuit

Polarization-based fiber optic sensors typically involve an extrinsic birefringent component to perform the actual polarization modulation. Intrinsic types of sensors include Faraday rotation and some Bragg gratings, which are written in polarizing-maintaining (PM) type. A method is developed to make an optical fiber that only transmits fully linearly polarized light and maintains the polarization state. The method for efficient ingesting laser into this fiber is also reported. Using an optical fiber with a prism head, we can compress a plane wave into the thin. Polarization of light carries vital information in numerous scientific disciplines, including biomedical imaging, optical diagnostics, and environmental sensing. Also highlighted was the concept of describing the light energy as a combination of two degenerate.
