Some of the greatest unanswered questions about the nature of the universe are related to light, the vacuum (i.e. space where neither matter nor radiation exists), and their relationship with time. In the past, physicists ...
Circulators are important components in communication technology. Their unique way of routing light usually requires centimeter-sized magnets, which are difficult to miniaturize for use on optical chips. Researchers at AMOLF ...
