Optical Isolator Guards Against Unwanted Reflections
CAMBRIDGE, Mass., June 30, 2023 — An optical isolator developed at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) could drastically improve optical systems for many practical applications. Many optical systems, such as those used for telecommunications, microscopy, imaging, quantum photonics, and more, rely on a laser to generate photons and beams of light. To prevent those lasers from damage and instability, these systems also require isolators, which are components that prevent light from
