Off resonant Fano enhanced single molecule resolution imaging with a CW source
Rasim Volga Ovali, Taner Tarik Aytas, Ramazan Sahin +1
Apertureless scanning near-field optical microscopy (a-SNOM) is typically limited to ~10 nm resolution by the tip apex size. We demonstrate that ~1-nm resolution can be achieved un…
Optically tunable linear and nonlinear enhancement of index of refraction
Elif Ozturk, Hira Asif, Mehmet Gunay +2
Control of optical properties of materials by tuning their refractive index can revolutionize the current state-of-the-art technology to manipulate light propagation in the high lo…
Surface plasmon polaritons with extended lifetime
Rasim Volga Ovali, Mehmet Emre Tasgin
The propagation distance of surface plasmon polaritons (SPPs) on metal nanowires is severely limited by their short lifetime, primarily due to strong metallic losses. In this work,…
Voltage-controlled extraordinary optical transmission in the visible regime
Hira Asif, Alpan Bek, Mehmet Emre Tasgin +1
Control of components in integrated photonic circuits is crucial in achieving programmable devices. Operation bandwidth of a plasmonic device cannot be generally tuned once it is m…
All-Optical Control of Ultrafast Plasmon Resonances in the Pulse-Driven Extraordinary Optical Transmission
Hira Asif, Mehmet Emre Tasgin, Ramazan Sahin
Understanding the ultrafast processes at their natural-time scale is crucial for controlling and manipulating nanoscale optoelectronic devices under light-matter interaction. Here,…
Silent-enhancement of multiple Raman modes via tuning optical properties of graphene nanostructures
Asli Gencaslan, Taner Tarik Aytas, Hira Asif +2
Raman scattering signal can be enhanced through localization of incident field into sub-wavelength hot-spots through plasmonic nano-structures (Surface-enhanced Raman scattering-SE…
