Quantum photonics by serendipity

A photonic chip with no less than 128 tunable components proves to be a true computing "Swiss army knife" with a variety of applications. During her research on measuring light wavelengths using this photonic chip, Caterina ...

An all-optical neural network on a single chip

A team of researchers from the University of Münster, the University of Oxford and the University of Exeter has built an all-optical neural network on a single chip. In their paper published in the journal Nature, the group ...

Nonlinear integrated quantum electro-optic circuits

Physicists envision that the future of quantum computation networks will contain scalable, monolithic circuits, which include advanced functionalities on a single physical substrate. While substantial progress has already ...

Light connects two worlds on a single chip

For the first time, researchers of the University of Twente succeeded in connecting two parts of an electronics chip using an on-chip optical link. A light connection could be a safe way of connecting a high-power component ...

Novel laser technology for microchip-size chemical sensors

Most lasers emit photons of exactly the same wavelength, producing a single color. However, there are also lasers that consist of many frequencies, with equal intervals in between, as in the teeth of a comb; thus, they are ...
