Abstract

At the microscopic scale, the light matter interaction may organize colloidal matter due to a process known as optical binding. Optical binding has now been established as an important issue for the assembly of colloidal matter by light. In the paper we investigate one dimensional optically bound matter of microscopic objects. We develop a dual beam optical fiber trap using a femtosecond laser where the peak power permits us to use two-photon excitation within the host medium. In this trap we can visualize the field distribution in an optical bound array. A numerical model is presented which provides a comparison between theory and experiment.
