Photonic crystals is one application for multiphoton polymerization (MPP). The MPP technique enables the production of arbitrary shaped 3D structures from various polymers. The single linewidth of the woodpile photonic crystal shown in the illustration is lower than 200 nm. As the dimensions of the feature resolution could be comparable to the wavelength of visible light, alternating periodic structures such as photonic crystals can be made which can serve for modulating the light path. Various photonic devices can be made by employing MPP.
Multiphoton-polymerization (MPP) is a technology that enables the production of arbitrary shape polymeric structures within submicrometric resolution. First, a photoresist sample is prepared by drop-casting polymer material mixed with a photoinitiator on the glass slide and then pre-baking.
A feasibility study is composed of several steps, including researching methods for fabricating micro-structures, fabricating a micro-structure prototype, measuring and aligning the prototype with technical requirements, and finally preparing a study report.
