Isolator Wave Guide - Optical Isolators for PICs

Bulky optical isolators are now a thing of the past! Isolator Wave Guides (IWG) are tiny yet efficient latched garnet crystals that can guide light seamlessly in PICs. At the heart of IWGs are waveguides meticulously inscribed by femtosecond laser processes. This produces garnet slabs with preserved Faraday rotation characteristics and can guide light like any other waveguide. No more complex/costly lens alignments! IWG enables the integration of lasers into PICs without actively aligned lenses. This protects your fibered systems from optical back-reflections and feedback. IWG is easy to install and maintain, making it suitable for telecom and datacom applications.

Design flexibility IWGs can be tailored to meet individual customers’ unique needs and requirements. The compact lens-less design and the flexibility of IWG isolators’ mounting options can be easily

integrated into existing systems, reducing costly modifications. Leap over the final barrier and embrace the future of photonic integrated

circuits! Let’s talk. sales@aeponyx.com

UFO Probe® Vertical: Jenoptik presents new version of its probe card test solution for PIC wafer-level testing

With the new UFO Probe® Vertical, Jenoptik is expanding its portfolio of probe cards for testing photonic integrated circuits (PICs) at wafer- level. Like the previous probe cards, the vertical version is based on the innovative UFO Probe® Technology. This combines

smaller chips with significantly more and therefore smaller and more densely packed electrical contacts. With the UFO Probe® Vertical up to 6000 bond pads with dimensions down to 35 microns can be contacted. Depending on the needle type, even more. Also, solder bumps and copper pillars are no problem. The smallest addressable pitch of the electrical contacts is in the range of 40 to 80 microns. In addition, the vertical probes provide a lower and more uniform contact resistance in the range of 0.2 to 1.0 ohms, depending on the probe type, while minimizing probe marks. These further developments ensure economical use in high- volume test scenarios and ATE operability. www.jenoptik.com

a position-insensitive optical concept with

proven needle technology in a single probe card and is specifically designed for use on standard wafer probers. The consistent advancement of the technology expands the possibilities of optical coupling: the new probe card version combines the innovative optical concept with the vertical needle technology of established probe

new feature is the ability to include polarization preservation for individual or all optical channels. By incorporating the vertical needle technology, Jenoptik is responding to the increased market requirements, particularly with regard to co-packaged optics. Here, the trend is towards

card manufacturers. This allows the user to couple up to 32 optical channels in parallel as standard - or more if required - without the need for active alignment. It covers the entire wavelength range from 1260 to 1625 nanometers used in the telecommunications and data communications sector. Another
