Selective Enhancement of Optical Chirality and Spin Angular Momentum in Plasmonic Near-Field
Naoki Ichiji, Takuya Ishida, Ikki Morichika +3
The interaction between circularly polarized (CP) light and matter is governed by two fundamental quantities: spin angular momentum (SAM) and optical chirality (OC). While these qu…
Designing rotational motion of charges on plasmonic nanostructures excited by circularly polarized light
Naoki Ichiji, Takuya Ishida, Ikki Morichika +3
Rotational motion of charges in plasmonic nanostructures plays an important role in transferring angular momentum between light and matter on the nanometer scale. Although sophisti…
Frequency-Modulation Mode-Locked Laser with GHz Spectral Width Tunable in the 2-3 um Region
Zheyuan Zhang, Xiangbao Bu, Daiki Okazaki +3
A narrow-bandwidth actively mode-locked laser using a Cr:ZnS gain medium has been successfully demonstrated. A free-space electro-optic phase modulator is employed in the solid-sta…
Rotationally displaced electric field intensity distribution around square nanoantennas induced by circularly polarized light
Naoki Ichiji, Takuya Ishida, Ikki Morichika +2
An optical field around regular polygon metal nanostructures excited by circularly polarized light can exhibit rotationally displaced intensity distributions. Although this phenome…
