Intel introduced a semiconductor laser for 40 Gb / s networks

Intel introduced the world's first semiconductor laser, capable of providing modulation of the optical signal for data networks with a bandwidth of 40 Gb / s.
Photonic integrated circuits (PICs) are a much more cost-effective solution than options based on discrete components. If we analyze the history of the development of fiber-optic networks, we can conclude that it is the appearance of the corresponding PICs that provides the foundation for the wide dissemination of the next high-speed data transfer standard.
Intel has been at the forefront of the development of silicon-based optical modulators since 2004, when the company first proposed a similar device for use in equipment for networks with a bandwidth of 1 Gb / s. Then, in 2006, the release of PIC for 10 Gbit / s networks followed, and at the beginning of this year, data transmission at a speed of 30 Gbit / s was demonstrated. And now - the next barrier is taken, 40 Gb / s.
