@OhioStateECE Assistant Professor Shamsul Arafin presents a Solid State Electronics Program (SSEP) seminar on:

 “Compound III-V Semiconductor based Classical and Non-Classical Light Emitters at Visible through Mid-Infrared."

Location and time:

Noon in Dreese Labs Room 260

Abstract:

III-V compound semiconductor materials and photonic devices are expected to play an important role in addressing ongoing and future challenges in the field of communication and sensing. Ultra high-speed, short and long-range communication links; portable and power-efficient computing devices; solid-state lighting; ultra-fast interconnects; and high-performance optical sensors in sensing applications are critically depending on the success of next-generation emerging semiconductor materials and the resulting photonic devices. In this talk, I will mainly discuss about recent cutting-edge research efforts made by my team at OSU on III-V semiconductor materials and photonic devices. In particular, an emphasis will be given on nitride-based electrically­-pumped lasers with emission wavelengths of the ultraviolet and blue regions. Design, fabrication and testing results of such lasers will also be presented here. In addition, I will present the recent theoretical and experimental results of advanced antimonide-based lasers, being useful for sensing and defense applications. Considering a significant promise of quantum technologies, I will also briefly show how my research enters into the quantum territory for developing non-classical devices including single photon emitters that could enable robust communication-based applications, such as electronic warfare, signal intelligence, and counter-digital radio frequency memory.
