Photonics and Optoelectronics: Recent Advances and Future Prospects – A Review

Abstract

Photonics and optoelectronics represent a rapidly evolving interdisciplinary field at the interface of physics, materials science, and engineering. These technologies exploit the interaction of light with matter for information processing, communication, sensing, imaging, and energy applications. Recent advances in nanophotonics, plasmonics, photonic crystals, integrated optoelectronics, and quantum photonics have expanded the capabilities of devices such as lasers, photodetectors, modulators, and optical fibers. This review synthesizes contemporary research, highlighting material innovations, device architectures, and emerging applications. Fundamental limits, such as diffraction, optical losses, and energy conversion efficiency, are discussed alongside strategies for performance enhancement. A comparative analysis across photonic technologies provides insight into current trends and future prospects, emphasizing the role of nanostructured materials, hybrid systems, and quantum technologies in shaping next-generation photonics.
