Gratings and Planar Wave Guides

Planar waveguides (PWG) consist of sub-micron diffractive grating structures and high refractive index waveguides used as biochip substrates. Optics Balzers manufactures gratings with high uniformity across extended areas up to 5 inches, as well as coatings for waveguides that comply with low defect standards and biocompatibility. Support for customer specific design with optimized coupling and waveguiding can also be provided.
