Potential Due to a Polarized Object

Potential Due to a Polarized Object

A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...

Area of Science:

Nanophotonics and Plasmonics
Ultrafast Optics

Background:

Surface plasmon polaritons (SPPs) confine light to nanometer scales, enabling electric field enhancement and nanophotonic circuitry.
Temporal confinement is crucial for maximizing field strengths and achieving ultrafast switching in plasmonic devices.

Purpose of the Study:

To demonstrate few-cycle SPPs with high bandwidth and efficient coupling.
To achieve the shortest reported SPP wavepackets for advanced optical applications.
To spatiotemporally image and analyze the propagation dynamics of these ultrashort SPP wavepackets.

Main Methods:

Fabrication of a tapered plasmonic waveguide with an optimized grating structure.
Generation of few-cycle SPPs with >70 THz bandwidth and >50% light-to-plasmon coupling efficiency.
Time-resolved photoelectron microscopy with sub-10 fs temporal resolution for spatiotemporal imaging.

Main Results:

Observation of the shortest reported SPP wavepackets.
Full spatiotemporal imaging of co- and counter-propagating few-cycle SPP wavepackets.
Tracking of laser-plasmon phase evolution, demonstrating control via coupling conditions.

Conclusions:

The developed tapered plasmonic waveguide effectively supports and enables the observation of ultrashort SPP wavepackets.
Spatiotemporal imaging provides unprecedented insight into SPP dynamics and phase evolution.
This work paves the way for novel nanophotonic devices with enhanced temporal control over light.
