Seminar: Integrated Photonic and Plasmonic Devices for Sensing and Spectroscopy Applications

11:50 AM - 1:15 PM on Monday, April 7, 2014
Location: ICTAS 310 (Kelly Hall)

Ali Eftekhar, from Georgia Tech, will be the speaker.

Compact, sensitive, and low-cost sensing structures are of great interest for portable field sensing applications. Integrated photonic resonators offer a viable solution for monolithic lab-on-chip sensing due to their compactness, scalability, and high sensitivity. The compact size, high quality factor (Q), large free spectral range (FSR), high sensitivity to change in the refractive index of surrounding material, and relatively simple geometry of compact microdisk/micro - donut resonators, makes them a suitable option for on-chip spectroscopy and multiplexed sensing applications.

In this talk, Eftekhar will first present an overview of different research projects in the field of integrated photonics and plasmonic for signal processing and sensing applications at the photonic research lab at Georgia Tech. He will then focus on the application of resonance-based integrated photonic and plasmonic devices for on-chip spectroscopy, multiplexed gas and bio sensing, and coupled nano-plasmonic structures for high-efficiency surface-enhanced Raman scattering (SERS) sensing.
