Magneto Acoustic Spin Hall Oscillators

, 2018
This paper introduces a novel oscillator that combines the tunability of spin Hall-driven nano oscillators with the high quality factor (Q) of high overtone bulk acoustic wave resonators (HBAR), integrating both reference and tunable oscillators on the ...

Injection-locking dynamics of two self-pulsing nanocavities optically coupled on photonic integrated circuit

Communications Physics
Pulse generation in nanostructure devices underpins all-optical spiking neurons, on-chip communication, and sampling. Synchronizing such devices provides insights for implementing analog all-optical machines, at the cost of adding complexity to the ...

Bistable phase control via rocking in a nonlinear electronic oscillator

, 2006
We experimentally demonstrate the effective rocking of a nonlinear electronic circuit operating in a periodic regime. Namely, we show that driving a Chua circuit with a periodic signal, whose phase alternates (also periodically) in time, we lock the ...

Miniature Optical Atomic Clock: Stabilization of a Kerr Comb Oscillator [PDF]

, 2013
Mechanical clocks consist of a pendulum and a clockwork that translates the pendulum period to displayed time. The most advanced clocks utilize optical transitions in atoms in place of the pendulum and an optical frequency comb generated by a femtosecond

Stabilization of class-B broad-area lasers emission by external optical injection

, 2017
We theoretically examine the effect of external optical injection on the spatio-temporal dynamics of class-B broad-area lasers. We demonstrate that optical injection can efficiently stabilize the intrinsic transverse instabilities in such lasers ...
