Interference surface patterning using colloidal particle lens arrays

Not Accessible

Your library or personal account may give you access

Abstract

Surface patterns of complex morphology can be made by combining the near-field colloidal lithography and the multiple-beam interference of the incident laser light. Our calculation shows that patterns made of bright and dim photonic jets can be formed beneath the dielectric spheres within the close-packed colloidal monolayer. An algorithm to find the propagation directions, amplitudes, and phases of the incident beams needed to make the desired photonic jet pattern is proposed. The field contrast in those patterns is studied.
