Free-space data-carrying bendable light communications

Posted by in category: futurism

Bendable light beams have significant applications in optical manipulation, optical imaging, routing, micromachining and nonlinear optics. Researchers have long explored curved light beams in place of traditional Gaussian beams for line-of-sight light communications. In a recent study now published on Scientific Reports, Long Zhu and a team of researchers in Optical and Electronic information, in China, proposed and developed free-space, data-carrying bendable light communication systems between arbitrary targets for potential multifunctionality. The researchers employed a 32-ary quadrature amplitude modulation (32-QAM) based discrete multitone (DMT) signal to demonstrate free-space bendable light intensity modulated direct detection (IM-DD) communication in the presence of three curved light paths. They characterized (tested) multiple functions of free-space bendable light communication to reveal that they allowed optical communications to be more flexible, robust and multifunctional. The work will open a new direction to explore special light beams enabled, advanced free-space light communications.

Bendable light beams are a new class of electromagnetic waves associated with a localized intensity maximum that can propagate along a curved trajectory. Researchers have previously studied and reported generic classes of bendable light beams that travel along elliptical and parabolic trajectories. Airy beams (appear to curve as they travel) are a type of non-diffracting beams that maintain its wavefront during transmission, much like Bessel beams (which only exist in theory, ideally) for optical communication free of obstructions. Airy beams possess properties of self-acceleration, non-diffraction and self-healing to propagate along a parabolic trajectory. Aside from airy beams, bendable light beams can reconstruct their wavefront to propagate continuously along the preset trajectory. To explore advantages of bendable light beams for diverse applications, researchers must bend the light along arbitrary trajectories; which can be achieved using the caustic method.

Unique properties of quantum material explained for first time

Posted by in categories: nanotechnology, particle physics, quantum physics

The characteristics of a new, iron-containing type of material that is thought to have future applications in nanotechnology and spintronics have been determined at Purdue University.

The native material, a topological , is an unusual type of three-dimensional (3D) system that has the interesting property of not significantly changing its when it changes electronic phases—unlike water, for example, which goes from ice to liquid to steam. More important, the material has an electrically conductive surface but a non-conducting (insulating) core.

However, once iron is introduced into the native material, during a process called doping, certain structural rearrangements and magnetic properties appear which have been found with high-performance computational methods.

$30 Billion of Proof That India’s Tech Scene Is Back

Posted by in category: business

Hopefully the momentum at both PhonePe and Paytm will spur more Indian entrepreneurship, feeding a rebirth in India’s tech sector not seen since the IT-outsourcing boom two decades ago. While that gave us Tata Consultancy Services Ltd., Infosys Ltd., Wipro Ltd. and dozens more, most of those businesses focused on serving foreign needs.


Digital-wallet company PhonePe is preparing to spin out of the country’s biggest startup, Flipkart. A renaissance could be afoot.
