In conjunction with the 12th International Conference on Photonics, Optics and Laser Technology - PHOTOPTICS 2024
SCOPE
The interaction between light and small clusters of nanoscale metallic and/or dielectric components has been a recent subject of extensive experimental and theoretical research. Knowledge and understanding of the near- and far-field optical responses from individual and coupled nanoparticles have led to an unprecedented development in the fields of molecular optics, optical antenna design, surface enhanced spectroscopies, bio/chemical sensing, light guiding, solar cell system, information storage and other. Research of light-matter interaction at the nanoscale now presents an opportunity to build on the existing work or/and establish novel directions for this area of research.
We invite researchers to contribute with original research ideas that will stimulate the continuing reports to exploit the great potential that light-matter interaction have for real life applications but also to develop this field for future nanophotonic devices.

Brief Bio
Dr. Yoshito Tanaka is a Professor at Research Institute for Electronic Science, Hokkaido University. He received his Ph.D. from Osaka University in 2009 for his work on optical trapping and assembling of nanoparticles, such as J-aggregates, polymers, and metal nanoparticles, with a strongly focused laser beam. Prior to his present position since 2023, he started his careers a Postdoctoral Researcher at Hokkaido University (2009), held research fellowship for young scientists (JSPS) at Imperial College London (2013) and worked as a Specially Assigned Assistant Professor at Kwansei Gakuin University (2014) and then an Assistant Professor at University of Tokyo. After his Ph.D, his research focus on understanding and controlling the interactions between light and artificial nanostructures from the viewpoint of optical linear and angular momentum. Especially, his current interests cover optical forces and torques acting on the nanostructures, their application to nanoactuators, chiroptical response for spin and orbital angular momentum, nonlinear optical processes controlling the light momentum, and nanostructure control of Casimir forces.
Abstract
Optical forces arising from light momentum transfer in light-matter interactions are powerful tools for actuating micromachines. However, the requirements of focusing and steering an incident laser beam to engineer optical forces has bottlenecked the integration and implementation of the optically actuated machines. In this presentation, I will discuss plasmonic antennas that can control the momentum of the scattered light at deep-subwavelength scale and its application to nanoactuators that are independent of the momentum of the incident light. The nanoantenna can generate optical forces as a recoil of symmetry-breaking of the scattering patterns from the nanoantennas. Therefore, linear nanoactuators that move perpendicular to the incident light momentum and rotational nanoactuators driven by the incident light without angular momentum can be realized. In addition, engineering the behavior of localized plasmons enables unique optical forces, such as direction-controllable optical force according to the incident polarization direction and optical force depending on the refractive index of the surrounding medium.

Otto Muskens is a Professor of Physics at the University of Southampton. He received his PhD from the University of Utrecht in The Netherlands in 2004 and subsequently worked as a postdoctoral researcher at CNRS/Université Bordeaux in France and at FOM/AMOLF the Netherlands. In 2009 he started his position at the University of Southampton. From 2012 to 2017 he held an EPSRC fellowship on development of new concepts in silicon integrated photonics based on ideas from light scattering in complex media. In 2016 he held the Debye visiting chair at the University of Utrecht, he was elected Fellow of Optica in 2023. His current research interests span the domains of nanophotonics, metamaterials, silicon photonics, and light in complex media.
Abstract
I will present recent results on the development of nanophotonic platforms leveraging the 8-inch full-wafer processing capabilities of the University of Southampton’s cleanroom facility. Our research crosses over between free-space and integrated nanophotonics exploiting conventional technologies such as silicon with novel materials including doped metal oxides and phase change chalcogenides. Of particular interest is the exploration of low-loss materials for non-volatile switching such as antimony selenide, Sb2Se3, which was recently developed by our team.
Also I will present first results on the development of silicon metasurface optics leveraging the Nikon NSR-S204B DUV scanner, a unique capability in the UK’s academic research landscape which critical feature dimensions down to 200nm is very well suited to the fabrication of optical metasurfaces. Our recent work explores the design, fabrication and optical characterisation of metaoptics covering the short- and mid-wave infrared spectral range.
