Revealing the reason behind jet formation at the tip of laser optical fiber — ScienceDaily

When an optical fiber is immersed in liquid, a high temperature, high speed jet is discharged. Researchers expect this to be applied to medical treatment in the future. Now, a research team from Russia and Japan has explored this phenomenon further and revealed the reasons behind the jet formation.

Lasers using a thin optical fiber and combined with an endoscope and catheter can be easily transported into deep areas of the body or inside blood vessels. Traditionally, affected areas or lesions are removed by generating heat inside the tissue through laser absorption — a process known as the photothermal effect.

Yet, hydrodynamical phenomena, such as microbubble formation or high-speed jet generation from the optical fiber, show immense medical promise.

The process of jet formation happens when the laser is irradiated to the water, causing the water to boil and a vapor bubble to form at the tip of the optical

Physicists and chemists engineer optical fibers with 2D materials — ScienceDaily

At the latest since the Nobel Prize in Physics was awarded for research on graphene in 2010, 2D materials — nanosheets with atomic thickness — have been a hot topic in science.

This significant interest is due to their outstanding properties, which have enormous potential for a wide variety of applications. For instance, combined with optical fibres, 2D materials can enable novel applications in the areas of sensors, non-linear optics, and quantum technologies. However, combining these two components has so far been very laborious. Typically, the atomically thin layers had to be produced separately before being transferred by hand onto the optical fibre. Together with Australian colleagues, Jena researchers have now succeeded for the first time in growing 2D materials directly on optical fibres. This approach significantly facilitates manufacturing of such hybrids. The results of the study were reported recently in the journal on materials science Advanced Materials.

The most sensitive optical receivers yet for space communications — ScienceDaily

Communications in space demand the most sensitive receivers possible for maximum reach, while also requiring high bit-rate operations. A novel concept for laser-beam based communications, using an almost noiseless optical preamplifier in the receiver, was recently demonstrated by researchers at Chalmers University of Technology, Sweden.

In a new paper published in the scientific journal Nature: Light Science & Applications, a team of researchers describes a free-space optical transmission system relying on an optical amplifier that, in principle, does not add any excess noise — in contrast to all other preexisting optical amplifiers, referred to as phase-sensitive amplifiers (PSAs).

The researchers’ new concept demonstrates an unprecedented receiver sensitivity of just one photon-per-information bit at a data rate of 10 gigabits per second.

“Our results show the viability of this new approach for extending the reach and data rate in long-distance space communication links. It therefore also has the promise to

Roccat put optical switches in an ultralight gaming mouse for $60

roccat-burst-pro-presspic-011

The Burst Pro has a translucent body to let its lights shine through. 


Roccat

PC gaming peripheral brand Roccat is following up its release of its first keyboards built with its own optical switches with a pair of gaming mice using those same switches. Like the new Vulcan Pro keyboards announced on Sept. 23, the $60 Burst Pro and $30 Burst Core mice use the company’s new Titan Optical switch that the company says registers mouse clicks up to 100 times faster than standard traditional mechanical gaming mice. UK pricing is £50 for the Pro and £25 for the Core; pricing wasn’t available for Australia but converts to AU$84 and AU$42. 

Both mice weigh in at 68 grams (2.4 ounces) and have the same ergonomic symmetrical shape. Roccat used a honeycomb frame to cut down on weight but then covered them with a translucent shell to keep dust and other

The long-awaited photonic technique could change the way optical technologies are developed and used over the next decade — ScienceDaily

The colloidal diamond has been a dream of researchers since the 1990s. These structures — stable, self-assembled formations of miniscule materials — have the potential to make light waves as useful as electrons in computing, and hold promise for a host of other applications. But while the idea of colloidal diamonds was developed decades ago, no one was able to reliably produce the structures. Until now.

Researchers led by David Pine, professor of chemical and biomolecular engineering at the NYU Tandon School of Engineering and professor of physics at NYU, have devised a new process for the reliable self-assembly of colloids in a diamond formation that could lead to cheap, scalable fabrication of such structures. The discovery, detailed in “Colloidal Diamond,” appearing in the September 24 issue of Nature, could open the door to highly efficient optical circuits leading to advances in optical computers and lasers, light filters that
