I realize this might be a new concept, but GaN-based lasers, which are visible light semiconductor lasers that use semi-polar gallium nitride, have the potential to transmit data two to three times faster than standard blue lasers. The main goal of the project is to utilize Kyocera's technology to achieve higher precision and multiplexing, enabling the transmission of large amounts of data at high speed and efficiency. This would lead to significant reductions in time and costs.

Nishikawa:
Simply put, we are building an environment that allows optical wireless communication underwater and in the ocean. Currently ROVs（unmanned submersibles）

require an environment where they can communicate wirelessly, taking into account the weight and load of the communication cables, as well as the risk of the cables getting tangled. However, acoustic communication has huge latency and slow data rate, and its control is not easy due to multi-path. We believe that underwater wireless optical communication using GaN-based lasers can solve these issues. If successful, this system could support daily life by facilitating energy and infrastructure facility inspections, aid in the development of the fisheries industry through smart aquaculture, and enable monitoring of microplastics, CO2 levels, and seafloor fluctuations, potentially leading to better earthquake prediction.
