Photonics study involves the use of radiant energy (such as light), whose fundamental element is the photon. In simple terms, photonic sensor is nothing but a device that senses light and releases electricity. It is the physical science of light (photon) generation, detection, and manipulation through emission, transmission, modulation, signal processing, switching, amplification, and sensing. Due its superior qualities, photonic sensing technology used is increased in early-detection and early-warning systems for biological hazards, structural flaws, and security threats. It mainly focuses on the development of cutting-edge applications in diverse areas of safety and security, from biodetection to biometrics by providing comprehensive review of this evolving field. Edelweiss Publications accepts all the articles related to computer science and benefit the authors with more citation and global readers. Edelweiss Applied science and technology journal is a platform for authors to submit their valuable research work of material science and get global readers.
