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…
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…
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…
