Nonreciprocal devices are fundamental components that enable unidirectional signal flow in microwave communication systems by breaking Lorentz reciprocity. Such components—including isolators, ...

Researchers have published the demonstration of a fully-integrated single-chip microwave photonics system, combining optical and microwave signal processing on a single silicon chip. The chip ...

Metasurfaces, as 2D artificial electromagnetic materials engineered at subwavelength scales, enable efficient manipulation of electromagnetic waves far beyond natural materials, bridging the gap ...

Photonic approaches to microwave signal generation harness optical frequency combs, microresonator solitons and electro-optic modulation to derive gigahertz-rate carriers with phase noise far below ...
