Department of Electrical & Computer Engineering of The Ohio State University

Welcome to the home page of Optics & Photonics Research Lab (OPREL)



We are located in Caldwell Laboratory within the Columbus campus.
The group is led by Professor Shamsul Arafin.

We are a multidisciplinary research group working on III-V compound semiconductor technology for materials and devices: molecular beam epitaxial growth and characterization of thin films and nanoscale materials as well as the associated optoelectronic devices. Our research spans the areas of photonic integrated circuits, nanophotonic, semiconductor diode lasers, micro- and nanocavity light sources and quantum photonics. Various materials systems including, nitride, arsenide, phosphide and antimondie are used to petform this device level research. Materials are grown by Molecular Beam Epitaxy and Metal-Organic Chemical Vapor Deposition.

To learn more about us, our research, facilities, and capabilities, please explore our website. We hope you find these pages useful and informative and we welcome any feedback you may have!
