Kyocera (京瓷) and Tohoku University (东北大学) developed laser annealing that integrates optical isolators onto silicon-photonics chips without damaging surrounding components.

Kyocera (京瓷) and scientists at Japan’s Tohoku University Research Institute of Electrical Communication (东北大学电气通信研究所) developed a new laser-annealing technique. The university referenced here is Japan’s Tohoku University.

The reported technique heats only the region requiring treatment, allowing optical isolators to be integrated directly onto silicon-photonics chips without damaging neighboring components. This is a chip-integration research result, rather than an announcement of a complete optical networking system.
