The Fraunhofer IOF at the SPIE Photonics West 2018

Fair-Highlights 2018

 

The Fraunhofer IOF will present photonic components and systems "Made in Jena" at the German pavilion (Booth number: 4529-29). Innovations from the fields of optical systems, micro- and nanostructured components, quantum technology and fiber technology are shown. On the following page you will find an overview of all Fraunhofer IOF exhibits and events.

 

Additive manufacturing of optical high-power components
for VIS-NIR-IR applications

 

An entire process chain for the production of, e.g., customized lightweight metal mirrors out of AlSi12, AlSi40, and Al6061 is developed, enabling the processing of substrates up to ∅ 230 mm by selective laser melting. Due to the lightweight design with stochastic or symmetric structures, a mass reduction of up to 75% is achieved. Manufactured mirrors of ∅ 150 mm exhibit high stability and stiffness along with surface roughness of <1 nm RMS and form deviation of <150 nm PV after post finishing.

Antireflection coatings AR-plas2®
for glass and plastic lenses

 

New organic-inorganic hybrid materials enable the manufacturing of antireflection coatings AR-plas2® for the 300 to 1500 nm spectral range on an industrial scale. A refractive index lower than 1.1 on the outermost surface of the nanostructured coating guarantees a low residual reflectance for a broad range of light incidence angles. Coatings AR-plas2® exhibit a high temperature and humidity resistance. They are especially suitable for strongly curved optical lenses.

Stable polarization entangled photon source
for quantum key distribution


Space suitable Entangled Photon Sources provide the basis for quantum communication. The hybrid and simple, but highly efficient source of polarization-entangled photons is based on a Sagnac Interferometer and spontaneous parametric down-conversion in bulk periodically poled potassium titanyl phosphate crystals, which is pumped by a 405 nm laser diode at 5 mW. More than 300.000 photon pair events per second are detected, while maintaining overlap fidelity with the ideal quantum state of 0.98.
