Laser Method Puts Optical Isolators Directly On Silicon Chips

Executive Briefing & Key Highlights

How do you add an optical isolator to a silicon photonics chip without exposing the entire chip to high temperatures? A laser-based process could solve it. Kyocera and Tohoku University have developed a technology to integrate optical isolators directly onto silicon photonics chips using laser annealing. The method locally heats the material needed to form […]
