Mitsubishi demos laser communication in satellite to satellite and to ground
Although microwave radio communication is extensively used in satellite to satellite communication and satellite to ground communication, RF radio communication faces challenges to fulfil the growing demand for bandwidth involving lot of video-content transmission. Japanese multi domain technology expert Mitsubishi Electric is developing optical communication technologies to increase the data capacity by 10 X compared to RF communication. Mitsubishi is also researching to increase the distance range of communication using optical means.
Mitsubishi Electric announced that it has successfully demonstrated laser optical frequency control using a new light source module, a key component of an envisioned high-capacity laser optical communication network to be deployed in outer space. The new module generated a 1.5-µm wavelength signal which was installed in the OPTIMAL-11 nanosatellite developed through an industry-academia collaboration and released from the International Space Station (ISS) on January 6. The use of a nanosatellite enabled the demonstration to be carried out faster and at lower cost than using a conventional large satellite.
