Uni-Traveling-Carrier Photodiode Based on MoS2/GaN van der Waals Heterojunction for High-Speed Visible-Light Detection

Takuya Kadowaki, Takahiro Serikawa, Akihide Ichikawa +5

Uni-traveling-carrier photodiodes (UTC-PDs), which utilize only electrons as the active carriers, have become indispensable in high-speed optoelectronics due to their unique capabi…

Gallium-nitride-based interference-filter-stabilized external cavity diode laser with a surface-activated-bonded output coupler

Hisashi Ogawa, Tatsuya Kemmochi, Tetsushi Takano

We report on an interference-filter-stabilized external cavity diode laser using a gallium-nitride-based violet laser diode. Surface-activated-bonded glass substrates were employed…

Observation of non-linearity of generalized King plot in the search for new boson

Koki Ono, Yugo Saito, Taiki Ishiyama +6

We measure isotope shifts for neutral Yb isotopes on an ultranarrow optical clock transition with an accuracy of a few Hz. The part-per-billion…

Logical Fallacy of using the Electric Field in Non-resonant Near-field Optics

Itsuki Banno, Motoichi Ohtsu

We find that the electric field is not a suitable physical quantity to describe the response of a non-metallic material in the study of non-resonant near-field optics. In practice,…
