Abstract (en)
[origin: WO2009141353A1] The general field of the invention is that of devices for focusing light with sub-wavelength dimensions comprising at least one focusing structure comprising a metal film comprising a first aperture passing through the film and of dimensions of an order of magnitude that are smaller than the wavelength of use of the focusing device. In the devices according to the invention, the focusing structure comprises at least one optical cavity disposed on the aperture so that, when the structure is illuminated by an optical flux at the wavelength of use of the device, a significant part of this flux is concentrated on the aperture by said cavity. Several embodiments are described using various types of cavity that may comprise plasmon reflectors.
