Researchers Break Record for Long-Distance Broadband Data Transmission over 4-Core Optical Fiber
A research team led by Benjamin J. Puttnam at the National Institute of Information and Communications Technology (NICT) reported that it transmitted data over a distance of more than 3000 km (1860 miles) at a rate of 319 Tbit/s and a transmission bandwidth of greater than 120 nm, across the S-, C-, and L-bands.

Nanostructures Allow High Harmonic Generation with Pulsed Lasers
Cornell University researchers have developed nanostructures that enable record-breaking conversion of laser pulses into high-harmonic generation. The work paves the way for new scientific tools for high-resolution imaging, as well as the study of physical processes that occur at the scale of an attosecond.

On-Demand Optical Singularities Strengthen Range of Applications
A group led by Federico Capasso at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) has broadened the study of optical singularities to include to zero-dimensional (point) and 2D (sheet) optical singularities. The group developed a way to engineer 2D singularity sheets on demand.
