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, İbrahim Asrın Üzgüç, Ulaş Eyüpoğlu +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,…

Voltage-tunable, femtometer-precision plasmo-mechanical displacement at fixed gap size

Rasim Volga Ovali, Mehmet Emre Tasgin

We propose an elegant method for continuous electrical-tuning of plasmo-mechanical displacement and squeezing without changing plasmonic gap size. Recent experiments bend the mecha…

Environmental-induced work extraction

Rasim Volga Ovali, Shakir Ullah, Mehmet Gunay +1

A local measurement extracts work as a backaction, e.g., in a system of two entangled cavities: first cavity, , comprises a piston and the measurement is carried out on the seco…

Electrically-programmable frequency comb for compact quantum photonic circuits

Shakir Ullah, Mehmet Emre Tasgin, Rasim Volga Ovali +1

Recent efforts have demonstrated the first prototypes for compact and programmable photonic quantum computers (PQCs). Utilization of time-bin encoding in loop-like architectures en…

Environmental-induced work extraction

Rasim Volga Ovali, Shakir Ullah, Mehmet Günay +1

A measurement can extract work from an entangled, e.g., two-mode system. Here, we inquire the extracted work when no intellectual creature, like an ancilla/daemon, is present. When…

Single-molecule-resolution ultrafast near-field optical microscopy via plasmon lifetime extension

Rasim Volga Ovali, Ramazan Sahin, Alpan Bek +1

A recent study shows that: when a long lifetime particle is positioned near a plasmonic metal nanoparticle, lifetime of plasmon oscillations extends, but, "only" near that long-lif…

A quantum emitter coated with graphene interacting in the strong coupling regime

Mehmet Günay, Vasilios Karanikolas, Ramazan Sahin +3

We demonstrate the strong coupling of a quantum dot and a graphene spherical shell coating it. Our simulations are the exact solutions of 3D Maxwell equations. Interaction produces…
