Photoluminescence properties of single Mn-doped CdS nanocrystals studied by scanning near-field optical microscopy (2005)

Ishizumi, Atsushi, Matsuda, Kazunari, Saiki, Toshiharu, White, C. W., Kanemitsu, Yoshihiko

We have fabricated Mn-doped CdS (CdS:Mn) nanocrystals embedded in Al2O3 matrices by sequential ion implantation and studied their photoluminescence (PL) properties by a scanning near-field optical...

Nano-optical probing of exciton wave-functions confined in a GaAs quantum dot (2004)

Saiki, Toshiharu, Matsuda, Kazunari, Nomura, Shintaro, Mihara, Masaru, Aoyagi, Yoshinobu, Nair, Selvakumar, ...

We have enhanced the performance of near-field scanning optical microscopy (NSOM) in terms of the spatial resolution and the sensitivity in signal detection. A careful preparation of an aperture-NSOM...

Design and optimization of tapered structure of near-field fiber probe based on FDTD simulation (2000)

Nakamura, Hiroaki, Sato, Tetsuya, Kambe, Hirotomo, Sawada, Keiji, Saiki, Toshiharu

The finite-difference time-domain method was employed to simulate light propagation in tapered near-field fiber probes with small metal aperture. By conducting large-volume simulations, including...
