About the author: Sen Yang is currently a Ph.D. student in Interdisciplinary Materials Science Program under the direction of Dr. Justus Ndukaife. Sen studies dielectric nanotweezers for nanoscale particles trapping and dielectric nanoantennas for biomaterial sensing applications. In recently published work, he proposed an all-dielectric nanotweezer based on quasi-bound states in the continuum (BIC) for low laser power optical trapping with negligible heating effect. The strong electromagnetic field enhancement and confinement permitted high trapping stability. This work paves the way for applying quasi-BIC systems to low-power sub-100nm-particle trapping and sensing applications.
