Abstract
The use of light-induced micro-motors or micro-propellers,showcasing non-contact and non-damaging characteristics,is garnering increased attention in biomedical,micro-machine,and environmental fields.The High-order Poincaré(HOP)beam,as a vector beam,provides a controllable driving force with adjustable orbital angular momentum and spin angular momentum.In this study,we present the spin of a self-assembled micro-propeller structure propelled by the HOP beam,enabling flexible control over rotation velocity and direction.Our findings reveal that modifications to the total angular momentum of the driving beam field or alterations in the micro-propeller blade structure can influence rotation velocity.This research offers an efficient and versatile approach for applications in optical micromanipulation and micromachinery.
