Microcomb-injected, pulsed lasers as variable microwave gears

Low-noise microwave signals are of critical importance in numerous applications such as high-speed telecommunication and ultrafast data processing. Conventionally, such signals are generated with bulky and delicate microwave ...

Spinning towards robust microwave generation on the nano scale

Spin-torque oscillators (STOs) are nanoscale devices that generate microwaves using changes in magnetic field direction, but those produced by any individual device are too weak for practical applications. Physicists have ...
