Paper Abstract

We show how confocal microscopy can be used as a simple, fast and flexible technique to fabricate multiple diffractive masks on a single plate. These masks are useful to make full bandgap photonic crystals with a woodpile structure in a single illumination step. The versatility for the control of the confocal microscope allows to define the illumination area and codify the features of the diffractive mask in a simple and straightforward way. The period of the diffraction grating can be easily established by modifying the illumination area. This allows to control the dimensions of the woodpile structures and consequently the bandgap spectral range of the fabricated structures.
