Light-matter interactions enable a number of technologies we use on a daily basis such as the internet and solid-state lighting. Therefore engineering the way light interacts with matter will lead to better and more efficient components and new technologies. Dr. Cubukcu’s group studies resonantly enhanced light-matter interaction on the nanometer length scales. He utilizes this in combination with mechanics and emerging 2D materials for novel devices and sensors. In this talk, Dr. Cubukcu will give representative examples of these multifunctional devices. He will present a new type of a graphene enabled multimodal biosensor that can measure protein-protein interactions in the full opto-electro-mechanical domain. This biosensor combines all the advantages of the single mode sensors and achieves a 100 times improvement in the linear sensing dynamic range. Secondly, he will talk about optomechanically controlled frequency doubler based on a monolayer MoS2. His group achieves ~5000 times enhancement of second harmonic generation in a doubly resonant Fabry-Perot (FP) microcavity. Dr. Cubukcu will present his recent results on acoustic phonon lasing and cooling in an optical Fano resonance metamaterial. This is achieved by simultaneous phononic and photonic metamaterial resonances coupled through a thermoplasmonic backaction mechanism.
Ertugrul Cubukcu received his B.S. and M.S. degrees in Physics from Bilkent University, Turkey and his Ph.D. degree in Applied Physics from Harvard University. Following his postdoctoral work at the University of California, Berkeley, he joined the faculty at the University of Pennsylvania in 2011, where he is currently an Assistant Professor of Material Science and Engineering and, by courtesy, of Electrical and Systems Engineering. He is the recipient of IEEE Photonics Society Young Investigator Award and TASSA Young Scholar Award. Dr. Cubukcu is the author or coauthor of over 50 journal and conference papers. His group explores the nanoscale opto-electro-mechanical devices and sensors that utilize unique features of nanoantennas and two-dimensional materials. His work has been featured in Optics and Photonics News, MIT Technology Review, Newsweek, Nature Photonics, and Laser Focus World.
