I am pleased to welcome Dr. Mous Bahrami who joined us on September 2018 as Postdoctoral researcher. Dr. Bahrami obtained his B.Sc. in Physics from Isfahan University of Technology which is one of the prestigious and highest-ranking universities in Iran. He ranked 10th and 13th in photonics and optoelectronics M.Sc. nationwide entrance exams respectively. He finished his M.Sc. in Laser and Plasma Research Institute (LAPARI) at Shahid Beheshti University, Iran. There he investigated quantum optical properties of graphene and its nanoribbons with both theoretical and computational methods. Later, he jointed as a researcher to Theoretical Quantum Nano Photonics group at ICFO Spain where he worked on nonlinear optical properties of novel 2D materials. He joined the Department of Physics of Concordia University to peruse his Ph.D. in the field of condensed matter to investigate light-matter interaction. There he worked on many-body effects such as single- and two-body collisions, electron interaction by impurities, phonons on optical and transport of 2D and 1D novel structures via developing quantum linear response theory.
We had a chance to collaborate on a joint project titled, “Anti-EPCAM Gold Nanorods and Femtosecond Laser Pulses for Targeted Treatment of Retinoblastoma” with the Department of Electrical and Computer Engineering and Department of Oncology in University of Alberta.Retinoblastoma is a cancerous disease that affects the retina, and primarily affects young children.
This work presents a new technique to treat retinoblastoma cancer that ties physics, biology and computational modellingusing gold nanorods and femtosecond laser pulses. Femtosecond laser pulses are delivered through the various components of the eye, and absorbed by the gold nanorods. Once the gold nanorods absorb the laser light pulse, they heat up and explode inside the cancer cells, leading to targeted destruction of retinoblastoma cells. The report on this project was accepted as is in the Advanced Therapeutics Journal and has been chosen to appear on cover.
I am pleased to welcome Arezou Rashidi who joined us on early march 2018 as Visiting PhD Research Student. Arezou is fourth year Ph.D. student in the field of Computational Nanophotonics in Physics Department at the University of Tabriz, Iran. She was recognized as a top student (1st rank) during her B.Sc. and M.Sc. In 2008, Arezou was awarded as National Exceptional Talent in Physics from University of Tabriz and since then she has been a member of National Exceptional Talent Club. Her current research projects are focused on Photonic Crystals and Graphene-Based Nanostructures. So far she has published several papers in different journals such as Superlattices and Microstructures, Applied Optics and The European Physical Journal B.
- I am pleased to announce that the Minor in Physics has passed all the institutional steps and will be officially at Nipissing University curriculum on September 2018. If you are interested to know more details about this program please feel free to contact me or refer to teaching tab on my personal website.
A figure from our published paper has been chosen to appear on cover 1 of the 14 August 2017 issue of Journal of Applied Physics. This paper was with the collaboration of Nanophotonics and Quantum Devices Group at The University of Alabama in Huntsville. “Optically saturated and unsaturated collective resonances of flat metallic nanoantenna arrays”, Journal of Applied Physics,122, 063102 (2017).

Title: “Tunable coupling between exciton-polariton and exciton-surface plasmon in hybrid systems consisting of VO2 nanoparticles and quantum dots”
Abstract: Vanadium dioxide (VO2) features a semiconductor to metal phase change characteristic that leads to an abrupt change in the particle’s optical properties. A hybrid system consisting of semiconductor quantum dot (SQD) and vanadium dioxide nanoparticle (VO2NP) can support the coherent coupling of exciton-polaritons and exciton-plasmon polaritons in the semiconductor and metal phases of the VO2NP, respectively. In this talk, we theoretically show that the controlling over the VO2NP phase change transition alters the SQD optical response drastically in comparison to a bare SQD. The results can be applied to the design of thermal sensors at the nanoscale.
Math Talk Series – 28 May, 2017 – 1:15pm to 2:30pm in room A129.Title: “Quantum Dot Nanophotonics”
Abstract: Quantum dots (QDs), known as artificial atoms, are nanoscale semiconductor materials with a unique size-tunable optical property. These unique size dependent qualities lead to a narrow photoluminescence spectrum in the range of visible to infrared light. QDs have attracted tremendous attention in the past few years for a variety of scientific and commercial applications such as biological sensors, quantum commuting, photovoltaic and light emitting devices. In this talk we present a brief description of QDs and their associated optical properties,highlighting the concept the size dependent photo-physical properties. We also show how the coupling of QDs with the other nanostructures can dramatically alter the QDs photoluminescence for further development of QDs for each respective application.
