Anapole mediated giant photothermal nonlinearity in nanostructured silicon
Tianyue Zhang, Ying Che, Kai Chen +14
Featured with a plethora of electric and magnetic Mie resonances, high index dielectric nanostructures offer a versatile platform to concentrate light-matter interactions at the na…
Giant optical nonlinearity in single silicon nanostructure: ultrasmall all-optical switch and super-resolution imaging
Yi-Shiou Duh, Yusuke Nagasaki, Yu-Lung Tang +14
Silicon photonics has attracted significant interest in recent years due to its potential in integrated photonics components (1,2) as well as all-dielectric meta-optics elements.(3…
Nonlinear plasmonics at high temperatures
Yonatan Sivan, Shi-Wei Chu
We solve the Maxwell and heat equations self-consistently for metal nanoparticles under intense continuous wave (CW) illumination. Unlike previous studies, we rely on {\em experime…
Resonant second-harmonic-generation circular-dichroism microscopy reveals molecular chirality in native biological tissues
Mei-Yu Chen, Mikko J. Huttunen, Che-Wei Kan +5
Conventional linear optical activity effects are widely used for studying chiral materials. However, poor contrast and artifacts due to sample anisotropy limit the applicability of…
