Key parts for large-capacity space optical communication: Innovative light source module!
ーUsing a laser light source with a wavelength of 1.5μm, the capacity, speed, and distance are ten times greater than those of radio communicationsー
-Successfully demonstrated the performance of a light source module in outer space-
This is a summary of Mitsubishi Electric’s disclosure information.
Real circuit of light source module:
We have developed a light source module as a key part of large-capacity space optical communication.
The light source module was mounted on a microsatellite, and in January 2023, the performance was successfully demonstrated in outer space.
Image diagram of ground and space optical communication network:
In recent years, the use of images taken by satellites has been increasing, such as disaster sites and forest resource protection.
Conventional radio satellite communications:
There were restrictions such as communication capacity, communication time, and communication distance.
To solve this problem, there is a need for high-capacity, high-speed space optical communication.
Overall structure of light source module for space optical communication:
The emitted laser light has a very short wavelength compared to radio waves.
The terrestrial reception antenna can be made smaller, the installation is easier, and the expansion of use can be expected.
Our light source module enables high-speed, long-distance communication with 10 times the capacity of radio communication.
Image of CubeSat “OPTIMAL-1”:
This time, we installed this 1.5 μm wavelength band laser light source module on the microsatellite OPTIMAL-1.
State of insertion from the ISS into outer space:
We have successfully demonstrated the performance of laser optical frequency control using space optical communication.
Even without participating in a large-scale space development project, we performed a low-cost demonstration in a short period of time.
