Researchers at the Massachusetts Institute of Technology have created a material that captures light and stops it in orbit. Now their new research gives further explanation of the basic physical mechanism of the process and connects it to others. It seems to be a wide range of unrelated phenomena. The research was published in the latest issue of Physical Review Letters.
According to a recent report by the physicist organization network, new research shows that this light capture process, including the polarization direction of the torsional light, is based on a vortex phenomenon similar to that of a tornado to a water vortex drain. In addition, analysis shows that this trapped state is more stable, easier to generate, and difficult to disturb than previously thought.
The researchers said: "People think that the state of this trap is very subtle and almost impossible to achieve. But it turns out that it can exist in a robust way."
In most natural light, the direction of polarization is considered to be the direction of vibration of the light wave and is fixed. This is the principle that allows polarized sunglasses to work: light reflected from one surface is selectively polarized in one direction, and then the reflected light can be sealed at right angles by a polarizing filter.
The researchers say, but in these trapped light crystals, the light entering material is polarized in a vortex that varies with the direction of polarization of the beam. Since the polarization is different at each point of the vortex, it produces a singularity called a topological defect, the center of which is the point at which the light is captured.
This phenomenon has the potential to create a vector beam that can potentially create small particle accelerators. The device can use these vector beam particles to accelerate and impact each other, or allow future desktop devices to implement a variety of high-energy experiments that now require miles of circular tunnels.
Researchers say they can also use a tool called a stimulated emission loss microscope to achieve super-resolution imaging and allow more channels of data to be sent through a single optical fiber.
60M laser distance measure is a very convenient tool for various types of applications in industries, construction and house decoration. Laser Distance Meter is a very useful device which gives accurate measurement of distance, area and volume especially in large areas such as rooms, apartments, buildings, real estates, factories, warehouses, infrastructures, gardens, roads, and many other applications requiring accurate results for distance , area and volume measurement. Equipped with optical curved lens, features high light transmittance to ensure more accurate distance laser measurement. Measure distance up to 30~150m and just need 0.1~3s to get a quick result.
