Abstract
We report on experimental verification of optical trapping using multiple b eams generated by a vertical-cavity surface-emitting laser (VCSEL) array. C ontrol of the spatial and temporal emission of a VCSEL array provides flexi bility for manipulation of microscopic objects with compact hardware. Simul taneous capture of multiple objects and translation of an object without me chanical movement are demonstrated by an experimental system equipped with 8 x 8 VCSEL array sources. Features and applicability of the method are als o discussed. (C) 2001 Optical Society of America.
