Micro-optics

Femtosecond microfabrication technology is used in micro-optics applications, including multi-photon polymerization (MPP) and 3D laser lithography. MPP enables the production of polymeric structures with high resolution, such as Fresnel lenses and photonic crystals. These structures can be used in optics and photonics applications for miniaturization. 3D laser lithography is used to fabricate micro-optical components, such as micro prisms, which can be printed on functional devices for filtering and detecting light signals. Multiphoton polymerization provides flexibility in maintaining different quality and functionality surfaces for various applications.

Manufacturing examples

Photonic Crystal

The multiphoton polymerization 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.

Fresnel Lens

Microoptics is one of the applications for multi‑photon polymerization (MPP) technology. The illustrated lens has a diameter of 500 µm. Superb nearly spherical aberration-free focusing can be obtained in each Fresnel zone.

Prism for Elipsometry

Multiphoton polymerization is a flexible technique that allows different quality and various functionality surfaces to be maintained on the same structures depending on the needs of the application.

Employed Processes

Multi-Photon Polymerization

Microfabrication by multi-photon polymerization is a direct laser-write technique which allows 3D structuring of photopolymers at the micro- and nano-scale.

Laser Nanofactory

Multi-Photon Polimerization

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.

Contract Manufacturing

Feasibility Studies

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.

Small Scale Production

Small-scale production is an essential step in the overall process of micro-structure fabrication, helping to ensure that the developed process is effective, efficient, and capable of producing high-quality micro-structures at scale.
