Welcome to the

Theoretical Nanophotonics & Plasmonics Group

We are a theoretical group conducting research in the exciting field of Nanophotonics and Plasmonics. Using electrodynamic calculations and a large variety of computational methods (such as FDTD, DDA, BEM, FEM, and Mie theory), we aim at investigating, designing, and understanding the optical properties of plasmonic-based, and nanophotonic systems. Our expertise goes from the modeling of electron energy-loss (EELS), cathodoluminescence (CL), optical, and surface-enhanced Raman (SERS) spectroscopies to the investigation of coupling mechanisms between elementary excitations (such as plasmon-exciton, plasmon-phonon, magneto-plasmon...) in hybrid nanostructures.


We are always looking for motivated students to join our research group. We strongly encourage students who have been admitted to UTSA to contact us quickly if they have an interest in joining our group.

Apr. 14 - Award
Emil has been recommended for the Office of Undergraduate Research’s UG Scholarship. This competitive award will allow Emil to continue working on his hybrid plasmonics project during the Summer 2017. Congratulations Emil!

Mar. 28 - Grant
A $3M DoD grant from the Office of Naval Research on which Dr. Large will be participating as a collaborator has been accepted. Dr. Large will be working, in collaboration with Prof. Rick Van Duyne at Northwestern University, on plasmonic-dielectric metamaterials for enhanced spectroscopy and controlled chemistry.

Feb. 1 - New member

Emil Penafiel, a Physics major, is joining the group as an Undergraduate Research Assistant. Emil will be working on hybrid plexcitonic nanostructures.

Jan. 25 - Upcoming conferences

Dr. Large will be presenting his research at the upcoming ACS Spring Meeting in San Francisco and at the MRS Spring Meeting in Phoenix in April.
