Optical manipulation on solid surfaces

Min Qiu

Westlake University

Optical manipulation of micro-objects on solid surfaces is challenging due to strong adhesion and friction forces, which dwarfs the optical force considerably by several orders of magnitude. By exploiting light-induced elastic waves, we have recently proposed a solution to this conundrum. Gold micro-plates were actuated on untreated micro-fiber surfaces by using nanosecond light pulses, exhibiting versatile locomotion modes, including rotation, translation, in-plane pose transition and spiral motion, or alternatively, by using modulated continuous-wave light, exhibiting swing-like motions with frequency-dependent mechanical mode profiles. The new actuation mechanism, featuring interactions between elastic waves and their induced friction force, was unveiled. Besides, since elastic waves are excited by optical absorption, potential issues associated with thermal effects (such as thermal damage and melting) have been addressed by exploiting two-dimensional topological-insulator (TI) Sb2Te3 plates adopting the similar plate-fiber systems. Specifically, in the high-power regime, the actuation behavior of the TI plates is remarkably different from that in the low-power regime dominant by the elastic-wave-driven mechanism. Upon ablation and melting, liquid-like motion can be observed, enabled by the Marangoni effects, which highlights the possibility of utilizing phase transition and interface energy profiles to achieve actuation. Moreover, the actuation scheme can be extended to solid environments beyond the fiber side-face to more generalized planer substrates. Specifically, both in-plane and out-of-plane locomotion of adhered microplates can be induced with inputs of nanosecond laser pulses in a vertical optical path set-up, demonstrating the general applicability of the elastic wave-driven mechanism. We envision that the proposed technique, on one hand, could inspire future developments in optical manipulation on solid interfaces through various heat-mediated routes, and, on the other hand, can be integrated into optical chips for many unique applications, such as mobile, reconfigurable optical switches and modulators.
