Alan Martin, Engineer Extraordinaire, once told me, “You never regret adding isolation between your circuits.” While he was speaking in the context of power supplies, the same goes for isolating ...

Designed specifically for high-voltage sensing, a new generation of optically isolated amplifiers make monitoring and system protection circuits more accurate and easier to design. These iso-amps can ...

Researchers at Michigan Tech have mapped a noise-reducing magneto-optical response that occurs in fiber-optic communications, opening the door for new materials technologies. Optical signals produced ...

A new level of optical isolation necessary to advance on-chip optical signal processing has now been demonstrated by researchers. The technique involving light-sound interaction can be implemented in ...

Optical isolation and nonreciprocal devices are pivotal components in modern photonic systems, ensuring unidirectional light propagation and safeguarding sensitive equipment from unwanted reflections.

This simple circuit provides better than 1% accuracy in optically coupling a DC voltage signal. To compensate for the non-linearity of the optical isolator, an identical device is connected in the ...

Traditional computers are fast, but nothing like the speed of light—at 186,000 miles per second, you can crunch numbers awfully quick. That’s a big reason why optical photonics are being used for ...

Spun off from a laboratory at Inha University in South Korea, PhotoniSol, a dynamic startup, is leading the charge in silicon photonic integrated devices. The company focuses on commercializing a ...

Tiny circuits can go the distance. Researchers have mapped a noise-reducing magneto-optical response that occurs in fiber-optic communications, opening the door for new materials technologies. Optical ...

Nonlinear optical materials such as silicon can be used to make on-chip devices that break dynamic reciprocity. (Courtesy: K Xia) A new method for making devices that act like a “one-way street” for ...
