Narwhal-shaped wavefunctions describe a unique way of confining light to extremely small spaces. The mode volume measures how ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...

In a major breakthrough, scientists have observed a strange and previously theoretical form of light — known as negative light. This marks the first time in human history that such a phenomenon has ...
