    "abstract": "We present an optical interference model to create chiral microstructures\n(spirals) and its realization in photoresist using holographic lithography. The\nmodel is based on the interference of six equally-spaced circumpolar linear\npolarized side beams and a circular polarized central beam. The pitch and\nseparation of the spirals can be varied by changing the angle between the side\nbeams and the central beam. The realization of the model is carried out using\nthe 325 nm line of a He-Cd laser and spirals of sub-micron size are fabricated\nin photoresist.",
