Method and apparatus for detecting outliers in a set of runs of software applications

The invention relates to the writing and optical reading of high-density information. The higher energy density at the center of the reading laser beam is used for modifying the energy structure of an active layer in such a way as to make it capable of bearing surface plasmons. The coupling of the laser beam and the active layer thus modified can then excite surface plasmons in an interface between a dielectric layer and the active layer. These surface plasmons are disturbed by physical marks having very small dimensions and written in the optical storage medium; these disturbances generate a remote-field optical response which can be detected by a detector. The operation is carried out in super-resolution, the surface plasmons being generated only at the center of the laser beam and not at the periphery. It is therefore possible to write and to read again marks having dimensions of size smaller than the theoretical resolution of the optical reading system.

A near-field detection optical component operating in transmission. It includes at least one portion () forming at least one grating () of diffraction microstructures () succeeding one another over several periods (p), this grating () being capable of converting evanescent waves (), which are established between the component and an object () located in the near field, when it reflects or emits radiation having a wavelength, into propagating waves (') by a diffraction effect during transmission through the portion () forming the grating () of diffraction microstructures (). The period (p) of the grating () being of the order of magnitude of the wavelength of the radiation.

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 limited by a planar surface and an object having nanometric dimensions arranged on the planar surface at the focus of said solid immersion lens. A light-opaque layer having a central opening 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.

Solid immersion lens and related method for making same

There is provided a solid immersion lens in a material of refractive index n1, having an effective dioptre () separating from a medium of refractive index n2, an optical axis, a virtual object focal point for a convergent optical beam entering the lens via the effective dioptre, this virtual object focal point being conjugate with a real image focal point. The dioptre () is defined by the equation &#x221a;{square root over (x+y)}&#x2212;n&#x221a;{square root over ((x&#x2212;a)+y)}=L, x, y are the coordinates of a point (I) of the dioptre () in a system (A, x, y) whose origin is the virtual object focal point (A) and whose abscissa axis is the optical axis (Ax), Particular application to reading, writing, reproduction of optical data.
