POET Teralight powers AI with 1.6T speeds in 2xFR4 and DR8 configurations to support the industry’s leading pluggable transceivers. Teralight removes wire bonds and active alignments of components, creating an elegant architecture that can reach 3.2T. Teralight is a system-on-chip with integrated drivers, EML lasers, multiplexer (if needed), MPDs and thermistor. Its power efficiency and low cost puts it at the forefront of optical-engine design.

Linear Apodizing Filters are used to eliminate undesirable intensity variations in optical systems. When inserted in front of a detector, the filter can be used as a soft slit to reduce diffraction patterns, eliminate detector saturation, and obtain a uniform light intensity to the detector. The filters have a constant density in one direction and variable neutral density filtering in the other direction. Bullseye® Apodizers are also available.

Ion beam processes are perfect for etching slanted surface relief gratings (SRG) either directly into waveguides or into master stamps for NIL. scia Systems’ RIBE process creates SRGs with constant slant angles, using reactive gases to control material selectivity and etch rate. Substrates are tilted to achieve the desired angle and structure design. By using reactive ion beam trimming, slant angle and etching depth across the substrate can vary.
