摘要： The invention relates to a device for trapping particles contained in a liquid (L) placed in a tank (4), characterized in that it comprises a substrate (2) that is transparent at a working wavelength, a thin layer (1) of material with non-linear optical properties that are reversible at the working wavelength and which is fixed to a first face of the transparent substrate (2) to form all or part of at least one wall of the tank (4), a device for forming an optical trap which comprises a laser source which emits a laser beam and means for forming a waist of the laser beam, the laser beam being incident upon that face of the transparent substrate that lies on the opposite side to the first face and the waist of the laser beam being formed in the thin layer (1), an evanescent electromagnetic field forming at the surface of the thin layer (1).

摘要： The invention relates to the optical writing and reading of high-density information. The method comprises using the highest energy density at the centre of the reading laser beam for modifying the energetic structure of an active layer in order to make it capable of bearing surface plasmons. The coupling of the laser beam and the active layer thus modified can then excite the surface plasmons in an interface between a dielectric layer and the active layer. The surface plasmons are disturbed by physical marks having very small dimensions and written in the optical storage medium (10). These disturbances result in a remote-field optical response that can be detected by a detector (22). The operation is carried out in super-resolution, and the surface plasmons are generated only at the centre of the laser beam and not at the periphery thereof. It is thus possible to write and read again marks having dimensions lower that the theoretical resolution of the reading optical system.

摘要： The invention generally pertains to the field of solid immersion lenses for optical applications in high resolution microscopy. The lens of the invention includes a spherical sector (1) limited by a planar surface (11) and an object (2) having nanometric dimensions arranged on the planar surface at the focus of said solid immersion lens. A light-opaque layer (3) having a central opening (31) with nanometric dimensions can be provided on the planar surface, said opening being centred on the focus of the solid immersion lens. The nano-object can be a tube or a thread having a cylindrical shape. The lens of the invention can be made using lithography techniques.
