International Workshop on UV and deep-UV plasmonics

We are going to hold an internation workshop on UV and deep-UV plasmonics, named UV-DUV Plasmonics and Nanophotonics Workshop (UPN2013) in Osaka University during Oct. 28-29, 2013.

New members at NaSpec in April 2013

Starting from April 2013, four new B4 students, Lim Yang Chau, Masahiro Ohnishi, Shinnosuke Saeki and Zen-ei Esaki, have joined our reserch group.

New members at NaSpec in October 2012

Starting from October 2012, LiChuan Huang (aka Lily) from the National Taiwan University has joined our research team as a Frontier Lab Exchange Student. She is going to stay with us for one semester.

Member left us in April 2012

A VIEWPOINT article in Oct. 2010 issue of "Optics & Photonics News"


We have recently had a cover page in "Laser & Photonics Reviews"


This cover art depicts local deformation of an isolated single-walled carbon nanotube that is pressed by the apex of a nano-tip. The vibrational frequencies originating from this locally pressurized volume are distinctly different from those originating from rest of the sample. By sensing this difference, it is possible to image the sample with an extremely high spatial resolution in tip-enhanced Raman microscopy. We have previously demonstrated a spatial resolution of 3-4 nm ( Nature Photonics, 3, 473 (2009).; and Phys. Rev. Lett., 102, 186101 (2009).) in optical microscopy.
