Abstract
Abstract: Here we present holographic fabrications of large area nano-optical device templates, including nano-antenna and photonic quasi-crystals using a single reflective optical element (ROE) through single beam and a single exposure process. These ROEs consist of several silicon wafers arranged with 5 or 6-fold symmetry, supported by two plastic platforms. By changing the polarization of the incident beam, various photonic quasi-crystal including spiral quasicrystals can be fabricated using the 5-fold symmetrically arranged optical element. Using the single optical element with silicon chips arranged in 6-fold symmetry, large areas of nano gap arrays can be fabricated holographically. These nanogaps and their shapes can be controlled through the phase delay of one laser beam. The nano gap arrays will be used for fabrication of nano-antennas arrays after metal depositions.
