Three-Dimensional Low-Index-Contrast Photonic Crystals Fabricated Using A Tunable Beam Splitter

Abstract

This paper describes the design and implementation of a tunable beam splitter for fabricating three-dimensional low-index-contrast photonic crystals using four-beam interference. Here, a central console is used to split a single laser beam into four beams that are focused onto the sample in an umbrella-like configuration using three adjustable mirrors. The design facilitates simple and precise adjustments of the beam angles and polarization, which can be used to readily optimize fabrication conditions for different photosensitive materials and lattice structures. Structures fabricated using this tunable beam splitter at two different incident angles of 18.5° and 27° resulted in lattices with hexagonal symmetries having well-defined nanometre-scale features that are in close agreement with the feature sizes predicted theoretically. © 2006 IOP Publishing Ltd.
