Photonic structure for embedded application: Realization of optical filter based locking system

Optical filter based locking system using photonic structure is explored in this research. Here, photonic structure is envisaged by the apt periodic combination of silicon and air. The proposed photonic structure interface with hardware implementation to realize the optical fiber based locking system. This paper emphasizes on both simulation outcomes which is investigated through reflectance characteristics and hardware implementation using Arduino board to display the lock/ unlock status. Finally, this work divulges that different type of locking system may be designed with varying the input parameters of photonic structures.
