New fibre optic technology to boost internet bandwidth

 

 Scientists have devised a new fibre optic technology that promises to increase internet bandwidth dramatically.

WASHINGTON:     

               In a breakthrough, scientists -- including one of Indian origin -- have devised a new fibre optic technology that promises to increase bandwidth dramatically, easing internet congestion and video streaming.

The technology centers on donut-shaped laser light beams called optical vortices, in which the light twists like a tornado as it moves along the beam path, rather than in a straight line.

Widely studied in molecular biology, atomic physics and quantum optics, optical vortices (also known as orbital angular momentum, or OAM, beams) were thought to be unstable in fibre, until Boston University engineering professor Siddharth Ramachandran recently designed an optical fibre that can propagate them.

In a paper in journal Science, he and Alan Willner of University of Southern California, demonstrated the stability of the beams in optical fibre and also their potential to boost internet bandwidth.

"For several decades since optical fibres were deployed, the conventional assumption has been that OAM-carrying beams are inherently unstable in fibres," said Ramachandran.
"Our discovery, of design classes in which they are stable, has profound implications for a variety of scientific and technological fields that have exploited the unique properties of OAM-carrying light, including the use of such beams for enhancing data capacity in fibres," he said.

Ramachandran and Willner collaborated with OFS-Fitel, a fibre optics company in Denmark, and Tel Aviv University.

Traditionally, bandwidth has been enhanced by increasing the number of colours, or wavelengths of data-carrying laser signals -- essentially streams of 1s and 0s -- sent down an optical fibre, where the signals are processed according to colour.

An emerging strategy to boost bandwidth is to send the light through a fibre along distinctive paths, or modes, each carrying a cache of data from one end of the fibre to the other.

Unlike the colours, however, data streams of 1s and 0s from different modes mix together; determining which data stream came from which source requires computationally intensive and energy-hungry digital signal processing algorithms.

Ramachandran and Willner's approach combines both strategies, packing several colours into each mode, and using multiple modes.

In experiments in the study, researchers created an OAM fibre with four modes (an optical fibre typically has two), and showed that for each OAM mode, they could send data through a 1km fibre in 10 different colours, resulting in a transmission capacity of 1.6 terabits per second.

A robot that views maps in 3D

                                     

                             

Researchers have developed humanoid robots in the world that maps reference relative to its surroundings.

LONDON: 

            Researchers have developed one of the most advanced humanoid robots in the world that maps reference relative to its surroundings and is able to "remember" where it has been before.

Computer vision algorithms enable the latest humanoid robot, Roboray, developed by researchers from the University of Bristol, to build real-time 3D visual maps to move around more efficiently.

The ability to build visual maps quickly and anywhere by using cameras is essential for autonomous robot navigation, in particular when the robot gets into places that have no global positioning system (GPS) signals or other references.

Roboray is one of the most advanced humanoid robots in the world, with a height of 140cm and a weight of 50kg. It has a stereo camera on its head and 53 different actuators including six for each leg and 12 for each hand, researchers said.

The robot features a range of novel technologies. In particular it walks in a more human-like manner by using what is known as dynamic walking. This means that the robot is falling at every step, using gravity to carry it forward without much energy use.

This is the way humans walk and is in contrast to most other humanoid robots that "bend their knees to keep the centre of mass low and stable." This way of walking is also more challenging for the computer vision algorithms as objects in images move more quickly.

"A humanoid robot has an ideal shape to use the same tools and spaces designed for people, as well as a good test bed to develop machine intelligence designed for human interaction," Dr Walterio Mayol-Cuevas, deputy director of the Bristol Robotics Lab, said.

"Robots that close the gap with human behaviours, such as by featuring dynamic walking, will not only allow more energy efficiency but be better accepted by people as they move in a more natural manner," said Mayol-Cuevas.

The technology of rapid 3D visual mapping is internationally renowned because of its ability to robustly track and recover from rapid motions and occlusions, which is essential for when the humanoid moves and turns at normal walking speeds, researchers said.

The study was published in the journal Advanced Robotics.
