Led flash light integrates the wireless keyboard technology

And near-infrared light-emitting semiconductor laser diode emission wavelength of 0.8 ~ 1.0m.
Future development needs to continue to raise the brightness, lower prices, improve service life and other issues.
Graduates to go: to master or doctoral degree; or to the Ministry of Information Industry, Chinese Academy of Sciences and the Institute, the telecommunications sector, universities, enterprises, institutions and related companies, mainly engaged in optics, optoelectronics, photonics technology, scientific, optical information engineering and technology, optical engineering and technology, optical signal detection processing and control technology and other fields of research, design, development, application and management. In microelectronics technology boom at the same time, it was discovered that you can use optical advantages for our respective services. green laser pointer integrates the wireless mouse technology.Such as lasers, photodetectors, solar cells and other aspects such as the need for optoelectronic integration. This is the early optoelectronics. With the development of optoelectronics, people study the full use of light to process information, so the birth of photonics. So it can be said, first with the optoelectronics, photonics, there has been. The final development will be re-unified optical, that is a higher level of optoelectronics. Is now developing a single electronic technology and single-photon technology, when the information carrier is no longer the beam, but the individual particles. Photons and electrons are the concepts of quantum mechanics, the difference is just a different wavelength. I think we in the twenty-first century will certainly get that far. led flash light integrates the wireless keyboard technology.At that time neither called photonic information technology, electronic information technology can not be called, should be called quantum information technology. Since photons with electrons do not have so many features Photonics has its unique advantages. Especially in the field of information. Such as communications, we are most used fiber-optic backbone network, the information carrier is light. As DWDM technology, the thickness of a human hair fiber can transmit one hundred million phone lines. This is the cable can not match. Another example of information storage technology, CD-ROM developed by the VCD to DVD, capacity increases several times in the future if developed to commercial blue laser, Blu-ray wavelengths of light as information carrier, you can also make the same size increased nearly ten times the capacity of the disc.green laser pointer could be applied in educational institutions. And light has coherence, holographic storage can be achieved in less than a square centimeter chip, we can Beijing library all the books kept inside. In computer terms, the future development trend of light to enter the computer, play the advantages of photonic switch to achieve the interconnection, using light to eliminate the bottleneck effect caused by electronic transmission. Optoelectronics, photonics technology is light band that infrared, visible light, ultraviolet and soft X-ray (frequency range 3 × 1011Hz ~ 3 × 1016Hz or wavelength range 1mm ~ 10nm) band electronics. After 80 years of photonics technology and its related technologies infiltrated each other after 90 years, has made its technology and application rapid development of information technology in the community playing an increasingly important role. green laser pointer could be applied in chambers.Facilitated by the CD-ROM technology in recent years, visible light semiconductor green laser pointer diodes and light emitting diode has been rapid development. Blue-green visible light semiconductor laser diode (LD) and blue-green semiconductor light-emitting diodes, light yellow orange-red laser diodes and high brightness visible light yellow orange green light emitting diodes have been commercialized.
