- Spin laser on an atomic scale: the image describes the laser resonator structure consisting of two types of nanoantenna structures. The radiation is trapped in the internal structure only (yellow). The active layer of the laser - a single atomic layer - is on the resonator. The laser beam is split into two beams by the opposite spins of the photons (light particles), which can be controlled with the help of the laser pump (credit: Scholardesigner co, LTD).

For the first time: a spin-optical laser at the atomic level - a new horizon for optoelectronic devices

The atomic structure of the material strontium vanadate (strontium vanadate) - illustration of the atomic structure of the material under tension (right) and compression (left). In the center you can see the true atomic arrangement in the material in an electron microscope image. At the bottom of the picture you can see how the various efforts change the structure of the energy levels in the material and therefore also the way the electrons arrange themselves in it. By controlling these properties, the researchers intend to engineer these materials into future transistors. Photo: Nitzan Zohar, Technion Spokesperson

Researchers at the Technion have developed tiny laser devices for small atomic clocks for the industry

  • No comments
These watches have unique features including small volume and weight and low energy consumption - essential features because they are mobile components powered by batteries. The tiny clock has uses similar to those of normal atomic clocks used for example in navigation systems (GPS), synchronization between communication systems and computer systems.

"Sliding and climbing between electrical polarizations": The periodic crystal structure contains a pair of atoms at regular intervals in each horizontal layer. Each additional layer can be slid to the right or left in the horizontal plane to place a blue atom exactly above a red atom or vice versa, thereby bouncing electrons with an electrical charge up or down between the layers. Unlike in polarized crystals known so far, the electric potential in the new system changes in a constant and well-defined value between each step. It is possible to climb in a controlled manner between all the different options, that is, it is possible to switch between the information units in the same crystal in contrast to a pair of modes in previous technologies.
