Controllable chiral light generation and vortex field investigation using plasmonic holes revealed by cathodoluminescence
Takumi Sannomiya, Taeko Matsukata, Naoki Yamamoto
Control of the angular momentum of light is a key technology for next-generation nano-optical devices and optical communications, including quantum communication and encoding. We p…
Time-correlated electron and photon counting microscopy
Sotatsu Yanagimoto, Naoki Yamamoto, Tatsuro Yuge +3
Electron microscopy based on high-energy electrons allows nanoscopic analytical imaging taking advantage of secondarily generated particles. Especially for cathodoluminescence, the…
Simultaneous nanoscale excitation and emission mapping by cathodoluminescence
Taeko Matsukata, Shintaro Ogura, F. Javier García de Abajo +1
Free-electron-based spectroscopies can reveal the nanoscale optical properties of semiconductor materials and nanophotonic devices with a spatial resolution far beyond the diffract…
Superbunching in cathodoluminescence: a master equation approach
Tatsuro Yuge, Naoki Yamamoto, Takumi Sannomiya +1
We propose a theoretical model of a master equation for cathodoluminescence (CL). The master equation describes simultaneous excitation of multiple emitters by an incoming electron…
Optical Spin Sorting Chain
Tatsuki Hinamoto, Minoru Fujii, Takumi Sannomiya
Transverse spin angular momentum of light is a key concept in recent nanophotonics to realize unidirectional light transport in waveguides by spin-momentum locking. Herein we theor…
Purcell effect of nitrogen-vacancy centers in nanodiamond coupled to propagating and localized surface plasmons revealed by photon-correlation cathodoluminescence
Sotatsu Yanagimoto, Naoki Yamamoto, Takumi Sannomiya +1
We measured the second-order correlation function of the cathodoluminescence intensity and investigated the Purcell effect by comparing the lifetimes of quantum emitters with and w…
