A New Laser Improve the Speed of Internet
When scientists invent a new laser that could speed up the network and take the place of fiber optical communication technology in the past 40 years, you must be excited.

Researchers from the California Institute of Technology have developed a new kind of laser that is capable of making Internet backbone speed four times faster. The new laser operates closer to a single frequency and has greater spectral purity. Spectral purity is a valuable index. The narrower the frequency range is, the more data it will transmit, which will lead to higher data speeds. In other words, it will provide a faster network.
The problems of current fiber optic networks
At present, most of the fiber optic networks use the distributed-feedback semiconductor, which was developed in the mid-1970s. The S-DFB once offered unprecedented spectral purity, but this purity will decrease as the S-DFB's III-V semiconductors absorbing light. Meanwhile, the demand for bandwidth is growing, so there must be some new technology to change this.
The advantages of new laser
The new laser developed by California Institute of Technology improves the original design by using a new silicon layer that does not absorb light and provide greater spectral purity. The frequency range has reduced to one twentieth of the S- DFB. There are many factors that can affect the Internet data transmission speed, it’s hard to say whether the speed will increase 20 times, but there is no doubt that the technology will improve the Internet speed.
Wide use of laser in domestic
Not only the communications industry, but also many other industries, the use of laser has rapidly expanded in many countries, China is no exception. Many domestic enterprises pay more attention to laser application, such as HUAGONG TECH Co., Ltd. The main business of HGTECH is industrial laser & CNC laser processing machine, opto-telecommunication device & information, electrical component, anti-counterfeit & information security technology, which comes from its main subsidiary such as HGLASER, HGIMAGE, HGGENUINE. Their market share takes the lead in the related industries.
So now, you can expect the omnipresence of laser technology in the future.
