Abstract

In this paper, we present new technique for modification of diffraction properties of light emitting devices by direct surface application of three-dimensional (3D) woodpile photonic crystal structure. For fabrication of woodpile structure, a commercial direct laser writing system Photonic Professional GT from Nanoscribe GmbH was used. This 3D laser lithography system is based on nonlinear two-photon absorption in liquid IP-Dip negative photosensitive polymer. Quality of prepared structure was analyzed using scanning electron microscope. The diffraction patterns of fabricated woodpile structure were measured using monochromatic light emitting diode and laser sources. After surface application on the output of the optical fiber, we investigated angular diffraction by goniophotometer.
