The good news: the first Chinese pieces of large size 940nmVCSEL epitaxial mass

China first piece of independent intellectual property rights 4 inch 940nm VCSEL vertical cavity surface emitting lasers in electricity production, the core extension of the successful trial, recently rushed to Taiwan and the mainland manufacturers downstream chip test. Since July 2016, the first piece of Chinese large size 6 inch PHEMT extension was born, by Dr. Zhang Yang, Professor Zeng Yiping composed of representatives of national independent science and technology team in core product line all the progress and technical strength has been achieved faster breakthrough, leading microelectronics optoelectronics group III-V large size extension industry with the international first-class science and technology into the core the era of intelligent technology.

Recently, the Apple Corp issued a iphone8 iphoneX VCSEL laser technology, VCSEL is causing widespread concern. The industry believes that the VCSEL products into the apple industry chain is not only a major breakthrough in the industry of the company's business, but also a major breakthrough in the field of consumption of semiconductor laser technology represented by VCSEL, VCSEL laser will enter the iPhone industry chain, optical devices will also benefit from the industrial field to consumption field.

What is the VCSEL laser? Vertical cavity surface emitting laser (Vertical-Cavity Surface-Emitting Laser, referred to as VCSEL, and the vertical cavity surface emitting laser) is a semiconductor laser, the laser is perpendicular to the top surface of injection, and general and independent chip, edge emitting laser emitted by the edge is different

From the birth of VCSEL as the core device of a new generation of optical storage and optical communication applications, which provides a new way for demand and optical storage density of the Internet continues to improve. With the development of VCSEL research and application requirements, VCSEL not only play an increasingly important role in the mobile phone, consumer electronics and other fields, VCSEL can also be used for face recognition, gesture sensing, 3D detection and VR (virtual reality) /AR (augmented reality) /MR (mixed reality). Of course, VCSEL the future can be widely used in networking, 5G communications, RF ADAS (advanced driver system components, etc.).

The development of optical communication field benefit from 40G and 100G communication technology, VCSEL laser market demand will be sustained development, but the market application in the future will be the largest field of intelligent mobile phone. Intelligent mobile phone VCSEL laser is expected in 2017 demand in 60 million, 2018 will rapidly increase to 120 million, 2014 will reach 240 million, basically keep doubling every year growth, far less than 50 million of the optical communication needs. In the field of optical communication, VCSEL laser application has become a trend, but now has the capability to launch a commercial product is accelink. The rapid development of 5G and networking, bring traffic data explosion for high speed and low power devices demand more and more high.
