AboutAbout the lab
Supporting high-capacity optical communication.
The Morita Lab studies optical communication technologies that underpin information and communication networks.
With the spread of 5G and the growth in traffic between data centers, the volume of data flowing around the world continues to increase.
The lab works on technologies that achieve high-capacity communication with limited energy, as well as optical communication technologies that can be used in new domains such as space and underwater.
Key terms
- Optical fiber
- A thin, thread-like communication line made of glass or resin that carries optical signals
- Low Earth orbit satellite
- An artificial satellite that flies in a low orbit, a few hundred kilometers above the ground
- Multiplexing
- A mechanism for sending multiple pieces of information together at the same time over a single communication line

ResearchResearch themes
The Morita Lab studies optical communication, a foundational technology that underpins information and communication networks. The lab works on technologies that achieve high-capacity communication with limited energy, and on optical communication technologies for new domains such as space and underwater.
*Illustrative imageEnergy-efficient, high-capacity optical communication
Optical communication systems are becoming ever higher in capacity, but their energy consumption is also rising. The lab studies technologies such as modulation, coding, and multiplexing to achieve high-capacity communication within a limited energy budget.
*Illustrative imageApplying optical communication in space and underwater
Beyond optical fibers on land and on the seafloor, the lab studies optical communication technologies for new environments, such as inter-satellite communication using low Earth orbit satellites and future deep-space communication with the Moon and Mars.
