Abstract

We demonstrate a generalized route to generate nanometer spatially confined ultrafast optical pulses with arbitrary deterministic femtosecond waveform control using surface plasmon polarition nanofocusing in 3D tapered noble metal tips.

Highlights

Plasmonic nanostructures as optical antennas have been proposed to overcome the size and mode mismatch between far-field propagating light and nanoscale quantum systems
We demonstrate a generalized route to generate nanometer spatially confined ultrafast optical pulses with arbitrary deterministic femtosecond waveform control using surface plasmon polarition nanofocusing in 3D tapered noble metal tips
As the nanofocusing mechanism itself relies on the spectral phase and polarization characteristics, this fundamentally limits the control of the optical transient that can be obtained on the nanoscale

Summary

Introduction

Plasmonic nanostructures as optical antennas have been proposed to overcome the size and mode mismatch between far-field propagating light and nanoscale quantum systems. We demonstrate a generalized route to generate nanometer spatially confined ultrafast optical pulses with arbitrary deterministic femtosecond waveform control using surface plasmon polarition nanofocusing in 3D tapered noble metal tips. Previous approaches to achieve nanometer control over ultrafast fields have relied on the use of appropriately shaped pulses to achieve spatial localization [1].
