Optically levitated micro and nanoparticles in vacuum offer new approaches for precision measurement andfundamental physics. We will discuss the use of rotational degree of freedom for achieving high Q values andstudying limit cycles.

10:00 AM - 10:45 AM (Wed. Aug 3, 2022 9:00 AM - 11:30 AM Main Hall (2/3))[Plenary2-C2] Fluctuation for Nanophotonics[Presentation Style] Onsite
1*Satoshi Kawata （1. Osaka University and RIKEN (Japan)）[Presentation Style] Onsite
In the field of nanophotonics, suppression of fluctuations in detectors, light sources, and the environment is
an important issue because they cause fatal errors in results. In this talk, I would like to discuss the positive
use of fluctuations rather as a signal source, using micro- and nano-Raman imaging and 3D-nanofabrication
as examples.

10:45 AM - 11:30 AM (Wed. Aug 3, 2022 9:00 AM - 11:30 AM Main Hall (2/3))[Plenary2-O3] Lens design for parallel super cameras[Presentation Style] Onsite
1*David J Brady , Jose Sasian1 （1. University of Arizona (United States of America)）[Presentation Style] Onsite
For compact gigapixel-scale cameras, multiscale lens designs are needed, but recent array camera designs
utilize discrete heterogeneous arrays. This presentation reviews heterogenous array designs and discusses
the motivation for this design choice.

space by tuning the triangle angle of 3D laser nanoprinted polymer triangles (named as nanofins) coated withgold. The plasmonic nature of the out-of-plane symmetry-protected BICs enables high field enhancement
