We’ve read a lot about oscillators, but crystal oscillators seem to be a bit of a mystery. Hobby-level books tend to say, build a circuit like this and then mess with it until it oscillates.

Optical parametric oscillators simultaneously generate two beams of coherent light that are widely tunable in wavelength. This flexibility makes them a popular tool in various areas of scientific ...

One emerging technology is macroscopic mechanical oscillators, devices that are vital in quartz watches, mobile phones, and lasers used in telecommunications. In the quantum realm, macroscopic ...

Oscillators are physical systems whose evolution over time varies repeatedly around a central state of equilibrium. Oscillating cycles that are more or less periodic are found in all sectors of ...

The researchers can generate and control the spin waves, enabling a phase controlled mutual synchronization between two so-called spin Hall nano-oscillators. By controlling the phase of these ...
