Imaging the field inside nanophotonic devices
Tal Fishman, Urs Haeusler, Raphael Dahan +9
Controlling optical fields on the subwavelength scale is at the core of any nanophotonic device. Of particular interest are nanophotonic particle accelerators that promise a compac…
Boosting the efficiency of Smith-Purcell radiators using nanophotonic inverse design
Urs Haeusler, Michael Seidling, Peyman Yousefi +1
The generation of radiation from free electrons passing a grating, known as Smith-Purcell radiation, finds various applications including non-destructive beam diagnostics and tunab…
Electron phase space control in photonic chip-based particle acceleration
Roy Shiloh, Johannes Illmer, Tomáš Chlouba +5
Particle accelerators are essential tools in science, hospitals and industry. Yet, their costs and large footprint, ranging in length from meters to several kilometres, limit their…
Imprinting the quantum statistics of photons on free electrons
Raphael Dahan, Alexey Gorlach, Urs Haeusler +8
The fundamental interaction between free electrons and light stands at the base of both classical and quantum physics, with applications in free-electron acceleration, radiation so…
Generation and Characterization of Attosecond Micro-Bunched Electron Pulse Trains via Dielectric Laser Acceleration
Norbert Schönenberger, Anna Mittelbach, Peyman Yousefi +2
Dielectric laser acceleration is a versatile scheme to accelerate and control electrons with the help of femtosecond laser pulses in nanophotonic structures. We demonstrate here th…
Dielectric-laser electron acceleration in a dual pillar grating with a distributed Bragg reflector
Peyman Yousefi, Norbert Schönenberger, Joshua McNeur +3
We report on the efficacy of a novel design for dielectric laser accelerators by adding a distributed Bragg reflector (DBR) to a dual pillar grating accelerating structure. This mi…
Ultrafast scanning electron microscope applied for studying the interaction between free electrons and optical near-fields of periodic nanostructures
M. Kozák, J. McNeur, N. Schönenberger +6
In this paper we describe an ultrafast scanning electron microscope setup developed for the research of inelastic scattering of electrons at optical near-fields of periodic dielect…
Silicon dual pillar structure with a distributed Bragg reflector for dielectric laser accelerators: Design and fabrication
Peyman Yousefi, Joshua McNeur, Martin Kozák +5
Dielectric laser accelerators (DLAs) have proven to be good candidates for miniaturized particle accelerators. They rely on micro-fabricated dielectrics which are able to modulate…
