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…

Electrical-control of third-order nonlinearity via Fano interference
Deniz Eren Mol, Ä°brahim Asrın Ãzgüç, UlaÅ EyüpoÄlu +6
Programmable photonic computers necessitate the integration of electrically-tunable compact components into the photonic devices. In the state-of-the-art photonic quantum computers…

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,…
