Abstract
The present invention provides a new approach for subwavelength cavity solutions. Employment of a reflecting metasurface based on plasmonic nanostructure elements changes the cavity resonance condition that currently causes restrictions on minimum length. The short length of wave propagation between the cavity walls is compensated by strong localization of electromechanical energy near the metasurface walls, which experience considerable phase shifts over a very small distance. Subwavelength 2D and 3D cavities find implementation as laser sources, optical parametric oscillators, interferometers, laser phase and frequency stabilizers, laser spatial and temporal filters, adaptive beam, and pulse shaping devices.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
