Modelling, design and fabrication of dielectric photonic crystal structures using temporally asymmetric shaped femtosecond laser pulses

We present high aspect ratio Fano-resonance structures for optical filter application along with their fabrication technique, design and numerical simulation. The structuring of photonic crystal elements using temporally shaped femtosecond laser pulses is described. Performance considerations for the presented device due to angular spread of a real optical beam are discussed in addition.
