Find out CPO’s 2025 scorecard and what lies ahead for this optical interconnect technology in 2026 and beyond.

Craig Morgan outlines why comparator clinical trials are useful and provides points to consider to ensure the best outcome. In clinical trials, a comparator drug (defined as ‘an investigational or ...

My last column (“Designing with comparators,” EDN, March 29, 2001, pg 56) discussed basic comparator theory, and this column adds hysteresis to comparators to eliminate multiple switching on the ...

Passive, lossy materials with positive index at real frequencies can be used to realize optical antimatter under complex frequency excitation. Our approach enables arbitrary complex \(\epsilon ,\,\mu\ ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...
