Disclosed is a method to modify the electrical conductivity of an organic and/or molecular material including the steps of providing a reflective or photonic structure and of placing the organic and/or molecular material in or on the structure. The method also includes providing a structure () which has an electromagnetic mode which is by design, or can be made by way of adjustment or tuning, resonant with a transition in the organic and/or molecular material () and controlling, in particular enhancing, the mobility of the charge carriers, and thus the electrical current, in the organic and/or molecular material (), by way of strongly coupling the material () to the local electromagnetic vacuum field and exploiting the formation of extended macroscopic states in the material.

Method and device to modify the electrical properties of an organic and/or molecular material

The invention relates to a device () for detecting the emission of a target particle () at an emission wavelength, said device comprising: a photo-detector (A,B) comprising a sensitive detection surface having a high optical index; wherein said target particle () can be positioned in the vicinity of said sensitive surface in an analysis medium () having a low optical index; said device being characterized in that it further comprises: a mask () covering said sensitive surface, said mask including at least one area () opaque at said emission wavelength and at least one hole (), said hole being capable of receiving the target particle; and in that the mask includes at least one interface;said device further comprising at least one groove (A,B) provided at said interface, each of said at least one groove surrounding each of said at least one hole.

An apparatus/method for producing fabric-like electronic circuit patterns created by methodically joining electronic elements using textile fabrication-like methods in a predetermined arrangement.

Apparatus comprising electronic and/or optoelectronic circuitry and method for realizing said circuitry

An apparatus for emitting light with a controlled directionality and optical divergence from at least one opening includes a light impervious surface structure having the at least one opening, a periodic or quasi-periodic surface topography including one or several surface feature(s) and associated with the at least one opening on the surface structure, whereby light emerging from the opening(s) interacts with surface waves on the surface structure (20) thereby providing controlled directionality and optical divergence of the emitted light.

Optical transmission apparatus with directionality and divergence control

A read/write head for an optical storage medium is provided. The read/write head comprises a waveguide having an end face and a plasmon-enhanced device provided on the end face of the waveguide. The plasmon-enhanced device comprises a metal film having a first surface and a second surface, the first surface being fixed to the waveguide end face, the metal film having an aperture provided therethrough. The metal film has a periodic surface topography provided on at least one of the first and second surfaces of the metal film. Light incident on one of the surfaces of the metal film interacts with a surface plasmon mode on at least one of the surfaces of the metal film thereby enhancing transmission of light through the aperture in the metal film which is directed onto and/or collected from the optical storage medium. A read/write head with an integral light source is also provided. The invention also provides an array of precisely aligned read/write heads, and an array of precisely aligned read/write heads with integral light sources, as well as side-emitting lasers and vertical cavity surface emitting lasers (VCSELs) with enhanced transmission.

An apparatus for enhanced light transmission is provided. The apparatus comprises a metal film having a first surface and a second surface, at least one aperture being provided in the metal film and extending from the first surface to the second surface. The at least one aperture comprises an entrance portion disposed on the first surface of the metal film and an exit portion disposed in the second surface of the metal film, each portion having a cross-sectional area in the plane of the corresponding metal film surface, wherein the cross-sectional area of the entrance portion is not equal to the cross-sectional area of the exit portion. A periodic surface topography is provided on at least one of the first and second surfaces of the metal film, the periodic surface topography comprising a plurality of surface features, wherein the geometry of each aperture entrance portion substantially matches the geometry of the surface features.
