"The inherent stability of the #terahertz beat frequency between the signal and idler fields of an optical parametric oscillator is transferred to a microwave frequency of a Kerr #soliton comb, and synchronization is achieved via a coupling #waveguide without the need for electronic locking."

"We illustrate the potential of these concepts by fabricating #nanostructures that are impossible to make with any other known method: #waveguide-coupled high-Q silicon photonic cavities that confine telecom #photons to 2 nm air gaps with an aspect ratio of 100, corresponding to mode volumes more than 100 times below the #diffraction limit. Scanning transmission electron microscopy measurements confirm the ability to build devices with sub-nanometre dimensions."

Waveguide: https://en.wikipedia.org/wiki/Waveguide
Structure that guides waves e.g. sound, light, radio waves, other EM waves w. min. loss of E by restricting E transmission to 1 direction

"Here we show that a leaky oscillation with #anisotropic perturbation rather can achieve completely zero crosstalk realized by subwavelength grating (SWG) #metamaterials. The oscillating fields in the SWGs enable coupling coefficients in each direction to counteract each other, resulting in completely zero crosstalk."
