Seeking Postdoctoral Researcher(W570)


Nanoscale Quantum Photonics Laboratory
Chief Scientist Laboratories
(Chief Scientist: Yuichiro Kato)

Research field and overview

The Nanoscale Quantum Photonics Laboratory focuses on exploring the physics underlying the operation of nanoscale photonic devices, with an emphasis on devices that utilize individual single-walled carbon nanotubes. We are interested in developing techniques for controlling photons at the quantum mechanical level, as well as demonstrating optical devices with novel functionalities that can only be achieved at the nanoscale.
