Researchers at CU Boulder have developed highly efficient optical microresonators that could support a new generation of powerful sensor technologies.
A microresonator is a microscopic structure designed to confine light in a small space. As light circulates inside, its intensity increases. When that intensity reaches a sufficient level, scientists can carry out specialized optical processes that enable sensing and other advanced functions.
