Emergent physical properties of low-dimensional nanostructures have served as major drivers of research in nanoelectronics and nanophotonics science and engineering for many years. These attributes have been often utilized to implement faster, more energy-efficient, and more complex (opto)electronic devices for a wide range of applications including optical communications, classical/quantum computing, sensing/imaging, and energy harvesting from renewable resources.


This seminar will discuss device application of several classes of novel nanostructures including graphene and graphene-like materials, nano-plasmonic structures, and metamaterials. We will discuss that highly localized interaction of electromagnetic radiation with the electronic structure of these nano-devices, particularly in 2D quantum materials like graphene, offer new avenues to access quantum coherence at the mesoscopic scale. In this new class of nanodevices, quantum-coherent correlations among electrons offer a variety of novel electronic, optical, magnetic, and chemical phenomena.


In this talk, I will elaborate on some of the fundamental physical properties of these structures, highlight several important device applications, and discuss my research with regards to their design, fabrication, and characterization. This will include nanophotonic devices for optoelectronic and sensing applications as well as nanoelectronic devices for information processing and metrology. 



Behnood is a Senior R&D Photonic Integrated Circuit (PIC) Design Engineer at Ciena where he is working on development of novel high-speed optoelectronic devices for the next generation of coherent optical communication systems.


He received his PhD from the Electrical and Computer Engineering department and the Institute for Quantum Computing at the University of Waterloo in 2010. Prior to his current position he was an R&D Electro-Optic Design Engineer at Lumentum, a Research Officer at the National Research Council (NRC), and held postdoctoral positions at the Center for Research in Photonics at the University of Ottawa and the Center for Nanophysics and Advanced Materials at the University of Maryland, College Park.


His research interests include III-V and Si photonic integrated circuits, graphene-based nanoelectronics and optoelectronics, nanophotonics and metamaterials, plasmonics, and microwave-photonic devices. Behnood has published more than 70 refereed journal and conference technical papers and is a recipient of the NSERC Postdoctoral Fellowship and Mike and Ophelia Lazaridis Fellowship. He is a Senior Member of IEEE and member of SPIE, OSA, and APS.
