3D photonic structures for optoelectronic applications

Photonics has become recently an intensively evolving area, where the possibilities of photonic structures or crystals (PhC) for integrated optoelectronics were found. An employment of three dimensional (3D) laser technology with combination of stable polymer resin enable printing of micro-optical and nano-optical components or other type diffractive structures for optoelectronic applications. In this paper, we demonstrate possibilities of 3D laser technology based on two photon polymerization for application in optoelectronics. We prepared two types of 3D polymer photonic structures, which was proposed for direct application on light emitting diode chip. We designed and fabricated Kagome and square lattice structures in 3D arrangement and we analyzed their properties in scanning electron microscope and by diffraction measurements.
