In their proof-of-concept device, consisting of an array of 20 tunable microresonators, the team demonstrated that each multiplexed microresonator produced high-quality entangled photon pairs as compared to the best resonators they produced in previous work — design elements of the components in that paper have found their way into Cisco Systems’ newly unveiled quantum entanglement chip.

Concentrating light in a volume as small as the wavelength itself is a challenge that is crucial for numerous applications. Researchers from AMOLF, TU Delft, and Cornell University in the USA have demonstrated a new way to focus light on an extremely small scale. Their method utilizes special properties of a photonic crystal and works for a broader spectrum of wavelengths than alternative methods.

Physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a compact laser that emits extremely bright, short pulses of light in a useful but difficult-to-achieve wavelength range, packing the performance of larger photonic devices onto a single chip.
