Researchers have developed a new chip-sized microwave photonic filter to separate communication signals from noise and suppress unwanted interference across the full radio frequency spectrum. The ...

A technical paper titled “Integrated microwave photonic notch filter using a heterogeneously integrated Brillouin and active-silicon photonic circuit” was published by researchers at University of ...

Photonic Dirac cone is a special kind of degenerate state with linear dispersion, which is ubiquitous in various two-dimensional photonic crystals. By introducing the spatial inversion symmetry ...
