US-made so far the thinnest semiconductor to create a new nano-laser

The thinnest semiconductors so far can be indirectly tiled on top of the optical cavity. US scientists have manipulated the thinnest (just three atoms thick) semiconductors to date to create a new type of nanometer laser that is not only more efficient, easier to manufacture, and compatible with today’s electronic devices. Researchers hinted that the study results for the ultimate production of light instead of electronic transmission of the next generation computing facilities laid a solid foundation. From medical to metal cutting to electronic products, lasers play a major role in this, but in order to meet contemporary computing, communication, imaging and sensing requirements, scientists have been willing to produce smaller and lower power consumption Laser system. Technical knowledge The University of Washington and Stanford University jointly developed this nano-laser, with only three atoms thick tungsten semiconductor as the light ‘gain data’, or to meet the above requirements.

‘The use of tungsten-based semiconductors in nanoscale lasers has been relatively recent, and the single-layer tungsten-based molecules are slim and ineffective in emitting light,’ said Wu Sanfeng, a principal investigator of the study. ‘Scientists have used it to make The transistor, the diode, the solar cell and so on, at the moment, starts with it to make the nanometer laser cnc machines for sale. Although nanosecond lasers are small and invisible to the naked eye, they can be used in a wide range of applications – from next-generation computing devices to implantable microchips capable of monitoring health conditions. However, previously developed nano-lasers used gain information, either thicker or embedded in the cavity of the light to capture the layout, making them difficult to make and not easy with the current circuit and computing facilities perfect integration. According to the physicist network March 25 (Beijing time) reported that the latest nano-laser used in the three atomic thickness of the semiconductor can be placed directly in the commonly used optical cavity, which can be part of the composition of the laser with the invalid Linked together. And, as long as 27 watts of electricity can let it emit light, energy efficiency is extremely high hydraulic busbar cutter. The combination of the study author, Assistant Professor of Electrical Engineering and Physics, University of Washington, Akhama Yumuda said that the new nano-lasers is another advantage is easy to make, but also with the common electronic devices in the original silicon things things; , The use of the atomic plate as a gain data not only allow it to be useful in general and to better control its properties drilling machine process. The latest nano-laser technology to scientists and short-distance optical communications to the photographer made a major step.

Next, they intend to laser light emission properties of a more in-depth study. Raw materials Researchers hope that they can further produce electric-driven nanometer lasers, and ultimately achieve the use of light instead of electronic computer chip and the motherboard to transfer messages. The current messaging process may lead to overheating, and may also waste a lot of energy, thus, including Facebook, HP and Intel and other data centers with a large number of giants are more energy efficient solution to the fun. The use of photons rather than electrons to transmit messages consumes less energy and is not expected to break the current bandwidth and energy constraints of next generation computing devices.
