Photonic crystal fibres (PCF) are strands of glass, not much thicker than a human hair, with a lattice of hollow channels running along the fibre. If they are continuously twisted in their production, they resemble a multi-helix. ...
Solitary waves – known as solitons – appear in many forms. Perhaps the most recognizable is the tsunami, which forms following a disruption on the ocean floor and can travel, unabated, at high speeds for hundreds of miles.
(Â鶹ÒùÔº)—A team of researchers with the University of Burgundy in France has shown that solitons can vibrate like real molecules when paired. They have published a paper describing their technique and findings in the ...
Optical solitons are special wave packages that propagate without changing their shape. In optical communications, solitons can be used for generating frequency combs with various spectral lines, which allow to realize particularly ...
By precisely controlling the quantum behavior of an ultracold atomic gas, Rice University physicists have created a model system for studying the wave phenomenon that may bring about rogue waves in Earth's oceans.
Plasma, the ionised state of matter found in stars, is still not fully understood, largely due to its instability. Astrophysicists have long sought to develop models that can account for the turbulent motions inside plasma, ...
When your heart beats, blood courses through your arteries in waves of pressure. These pressure waves manifest as your pulse, a regular rhythm unperturbed by the complex internal structure of the body. Scientists call such ...
When your heart beats, blood courses through your veins in waves of pressure. These pressure waves manifest as your pulse, a regular rhythm unperturbed by the complex internal structure of the body. Scientists call such robust ...
Research led by ANU on the use of magnets to steer light has opened the door to new communications systems which could be smaller, cheaper and more agile than fibre optics.
EPFL scientists have found a way to miniaturize frequency combs, realizing a new step toward miniaturization of such tools. Their device can measure light oscillations with a precision of 12 digits.
