In this talk, we will present our recent work on nanoplasmonic based biosensors and photodetectors. We will present a label-free, optical nano-biosensor based on the Localized Surface Plasmon Resonance (LSPR) effect that is observed at the metal-dielectric interface of silver nano-cylinder arrays located periodically on a sapphire substrate by E-Beam Lithography (EBL), which provides high resolution and flexibility in patterning. The resultant tandem structures are named after “Fairy Chimneys” rock formation in Cappadocia, Turkey. We will also report on UV plasmonic antenna integrated metal semiconductor metal (MSM) photodetectors based on GaN.
