Abstract
An optical system includes a nanocavity having at least one nanostructure shaped to provide sub-wavelength confinement of an electromagnetic optical field. The nanocavity is shaped and formed to host a bound state in the continuum to provide spatial concentration and temporal storage of the electromagnetic optical field at the at least one nanostructure via an eigenmode of the electromagnetic optical field in the nanocavity. A method is for processing an electromagnetic optical field.

An optical system comprising:
- a nanocavity having at least one nanostructure shaped to provide sub-wavelength confinement of an electromagnetic optical field, the nanocavity being shaped and formed to host a bound state in the continuum to provide spatial concentration and temporal storage of the electromagnetic optical field at the at least one nanostructure via an eigenmode of the electromagnetic optical field in the nanocavity.
A method for processing an electromagnetic optical field, the method comprising the steps of:
- shaping and forming a nanocavity such that the nanocavity hosts a bound state in the continuum of the electromagnetic optical field;
- providing the nanocavity with at least one nanostructure shaped to provide sub-wavelength confinement of the electromagnetic optical field;
- and
- supplying the electromagnetic optical field to the nanocavity such that the electromagnetic optical field is spatially concentrated and temporarily stored at the at least one nanostructure via an eigenmode of the electromagnetic optical field in the nanocavity.
