High-Frequency and Optical Devices as Key Devices for Information and Communication Technology (ICT)
In recent years, the amount of communication traffic has been growing due to significant progress in
broadband communications. In the fields of both wireless communications such as mobile phones and optical
communications such as fiber optical transmission, continuous research and development are under way to raise the
transmission rate, including: faster data transmission through the mobile telephone network, applications of GaN
devices to the communications infrastructure, transition from 1 Gbps to 10 Gbps optical communication system for
FTTH, and speeding up of long-distance communications from 40 Gbps to 100 Gbps. As key devices for information
and communication technology (ICT), high-frequency and optical devices will play an even more important role.
This issue presents the results of product development by Mitsubishi Electric in these fields.
