Our article, Direct observation of phase-free propagation in a silicon waveguide, featured on the cover of November’s issue of ACS Photonics, has received substantial media coverage. This paper marks the first observation of an infinitely long optical standing wave, an especially accessible physics demonstration for the general public. Below is a selected list of highlights:
