New tech builds ultralow-loss integrated photonic circuits

Encoding information into light, and transmitting it through optical fibers lies at the core of optical communications. With an incredibly low loss of 0.2 dB/km, optical fibers made from silica have laid the foundations of ...

Researching on-chip erbium-doped lithium niobate microcavity lasers

As a complement to silicon-based photonic chips, lithium niobate thin film (LNOI) has become a research hotspot in the field of optoelectronic integration due to its outstanding nonlinear, electro-optic, acousto-optic, piezoelectric ...

Researching the chips of the future

The chips of the future will include photonics and electronics; they will have bandwidth, speed and processing and computing abilities that are currently unthinkable; they will make it possible to integrate many other components, ...

New light amplifier can boost the potential of photonics

A new light amplifier developed at the University of Twente not only boosts the light signals on a photonic chip, but it also enhances the applicability of those chips. Thanks to stronger light signals, detector chips for ...

Wiring a new path to scalable quantum computing

Last year, Google produced a 53-qubit quantum computer that could perform a specific calculation significantly faster than the world's fastest supercomputer. Like most of today's largest quantum computers, this system boasts ...

Light-emitting silicon for photonic computing

If computers transmitted data using photons instead of electrons, they would perform better and use less power. European researchers are now studying a new light-emitting alloy of silicon and germanium to obtain photonic ...
