Can light itself cast a shadow? It may sound like a philosophical riddle, but researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow. The ...

Beam shaping in nanophotonic systems remains a challenge due to the reliance on complex heuristic optimization procedures. In this work, we experimentally demonstrate a novel approach to topological ...

Using the ski jump, the authors built beam scanners on chips called photonic integrated circuits (PICs). The cantilevers can be fabricated using processes that have been established for conventional ...
