Project TitleSynchronized Optomechanical Oscillator Network for Low noise Radio-Frequency Source
Track Code5050
Short Description

This invention demonstrates that two distinct silicon nitride micromechanical oscillators placed in a vacuum can be synchronized in both phase and frequency through coupling mediated purely by an optical radiation field.

 

Abstract

Nanoscale synchronization has a wide range of applications including timing, navigation, signal processing and computing. Micro and nanoscale synchronization mechanisms have the potential to be integrated with current nanofabrication capabilities and enable scaling up to network sizes.

 

Existing coupled micromechanical oscillators usually employ direct physical connections which suffer from limited range, neighborhood restriction and non-configurable coupling. This further limits the control, physical size and possible topologies when forming complex oscillator networks. To address these limitations, synchronization at the nanoscale has now been demonstrated using only light, not mechanics.

 

The invention demonstrates that two distinct silicon nitride micromechanical oscillators placed in a vacuum, spaced 400 nanometers apart, can be synchronized in both phase and frequency through coupling mediated purely by an optical radiation field. The tunability of the optical coupling between the oscillators enables external control of the dynamics and switching between coupled and individual oscillation states.

  

Furthermore, established and future micro-photonics techniques such as electro-optic and thermo-optic techniques can now be extended to switch, filter and phase shift the coupling of these oscillators. The robustness of this technology could enable a host of new nanoscale photonic capabilities.

  

Potential Applications

Tuned oscillator networks for sensing, signal processing and nanoscale integrated circuits.
