Abstract

Holographic optical tweezers permit the simultaneous control of multiple optical traps. In this paper we examine the use of such systems for the purposes of micromanipulation and assembly of microstructured materials. To this end, optically induced forces and torques on a variety of objects are evaluated using numerical and semi-analytical methods. In the following paper we describe implementations of these methods (the finite difference time domain and T-matrix methods respectively) and present some salient results before concentrating on a particular application that involves the use of entropic forces to promote aggregation between microspheres.
