Marko Lončar’s group at SEAS builds isolator in a lithium niobate-based optical chip. Micrograph of electro-optic isolator chip on thin-film lithium niobate. An optical isolator created at the Harvard ...

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

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 ...

A research group has discovered significant nonreciprocal optical absorption of LiNiPO4, referred to as the optical diode effect, in which divalent nickel (Ni2+) ions are responsible for magnetism, by ...

The high power PM fiber optical isolator (1064/1030/980 nm polarization-maintaining optical fiber isolator) is one of the most important passive components. The function of a PM optical isolator is to ...

Researchers have experimentally realized an optical effect predicted over 75 years ago: the Tellegen effect, where electric ...
