INTEGRated-OPTIcal components

Integrated optical structures for passive components are optical planar waveguide structures applied to glass or polymer substrates. Very compact and efficient components can be created this way, allowing high splitting ratios in a tiny space. Typical splitting ratios range from 1x2 to 1x64. While structured glass substrates are typically used in telecommunication market, polymer based components are mainly used for signal and data transmission in sensor applications, based on the core diameter of the chosen fiber and the applied wavelength

Components
XENLUX fiber optical components are primarily based on polymer substrates (optical chip) which contain the splitter structures and are designed for large-core fibres >100µm. They allow complex optical implementations in a very small format. The optical structure guarantees a high degree of repeatability.

Micro-optical bench

For implementation of multiple optical functions such as beam splitting, filtering, reflection and more in a very limited space envelope, XENLUX uses the high precision polymer structure as a so-called micro-optical bench. It serves as the basic building block for each of the components. In a first step, various types of coatings and mirrors can be applied directly on the chip which can then be completed by adding additional optical or electro-optical elements.

Key features:

• Proven, reliable technology
• Large degree of design flexibility in a tiny place
• Efficient optical implementation
• Reproducible, stable parameters
• Large quantity production
