All-optical switching of continuous-variable entanglement in an absorption-suppressed plasmonic nanodimer

Elif Ozturk, Mehmet Gunay, Ramazan Sahin +1

A subwavelength quantum-photonic circuit element should simultaneously generate nonclassical light, suppress plasmonic loss, and remain dynamically tunable. We show that an orthogo…

Detecting nonclassicality in randomly-displaced copies of a squeezed state

Mehmet Emre Tasgin

We address a fundamental question: Can one determine whether a received signal is squeezed when each copy arrives with a different displacement/amplitude? We introduce an interacti…

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…

Active tuning of ENZ resonances in meta-antenna through phase modulation of optical pulse

Elif Ozturk, Hira Asif, Mehmet Gunay +2

Plasmonic nanoantennas offer new avenues to manipulate the propagation of light in materials due to their near field enhancement and ultrafast response time. Here we investigate th…

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,…
