The Optomechanical Response of Nanostructured Materials
Abstract
The Optomechanical Response of Nanostructured Materials Kevin Webb Group, Purdue University West Lafayette, Indiana 47907, USA webb@purdue.edu The influence of nanostructured material on the optical force imparted is being investigated with a view to the development of new physical understanding and the enabling of applications. This project will facilitate applications that include propulsion, remote control, and low-energy communication. Experimental work has demonstrated that the pressure on a structured surface can exceed that on a perfect mirror. The physical understanding is that an asymmetric optical cavity effect leads to this increase. With the aid of a statistical analysis of aperiodic structures, insight into the relationship between the material and both the optical fields and the optical force density in the material has shed further light on how structured material can be used to regulate the optical force. Based on this analysis, it appears possible to have a negative pressure, and understanding can be found in the character of the field resonances. Within sight is an evaluation of basic photon momentum and force theory, and the frequency-dependent influences of material and structure. This will provide a design framework for applications.
