  • Method for Printing a Near Field Photoinduced Stable Structure, and Optical Fiber Tip for Implementing Same
    Publication number: 20080199126
    Abstract: The method comprises emitting appropriate polarisation light waves on a photosensitive material for inducing therein a topographic modification through an aperture of at the most 100 mm bound by an opaque area, said layer being arranged at the most 100 mm away from the aperture.

  • Method for printing a near field photoinduced stable structure, and optical fibre tip for implementing same
    Patent number: 7352384
    Abstract: The invention generally concerns a method involving emitting polarization light waves through an aperture with a dimension of maximum size lower than or equal to 100 nm, wherein the aperture is circumferentially bound by an opaque area that prevents the light waves from being propagated outside the aperture during use, and wherein the emitted polarization light waves (1) contact a material layer comprising a photosensitive compound whose surface is located at a distance lower than 100 nm from said aperture, and (2) induce a topographic modification of the material layer. In this manner, a stable structure is printed in relief in the material layer without requiring any additional development step. The invention is applicable, in certain embodiments, to ophthalmic optics.
