The optical vortex plays an increasingly important role in optical information processing. As an information carrier, it improves the capacity of channels and offers an independent aspect for analysis ...

A new working group set up by the Consortium For On-Board Optics (COBO) will try to establish optical waveguides as a viable technology for high-speed, board-level interconnects inside data centers.

Most Wi-Fi and Bluetooth designs will appear to work during board bring‐up, even if the antenna feedline has a horrible mis‐match, but then you get to range testing and data integrity ...
