In this paper, the process of thin film photopolymerization using evanescent waves is used and the adaptability of this process to pattern replication is studied. Variable frequency patterns are copied on film by an imaging process. After photopolyme

In the present work we report the results of holographic recording with two contra-propagating evanescent waves in photopolymers. The spatial frequency of the recorded permanent grating is 6380 mm−1 (grating step 156.7 nm) and 0.015% diffraction ef

Dry poly(vinyl alcohol) (PVA) formulations are widely used in the field of micro-optics for holographic recording and fabrication of micro-optical elements, but very little is known about the recording mechanism and even less in systems generating re

The fabrication of refractive microlenses with self-developing photopolymers is reported. A spatially controlled illumination of the photosensitive layer induced an inhomogeneous photopolymerization involving formation of 3-D polymer network, mass-tr

The use of a self-processing dry photopolymer layer capable of memorizing optical information as a local change in thickness, is proposed for the fabrication of microlenses, binary holograms and gratings. Relief micro-optical elements are generated b

A simplistic model of photopolymerization by evanescent waves (PEW) has been introduced in a previous paper. This model predicts a linear dependence of the polymerized thickness on the logarithm of exposure time. It provides the general trend of the

0Holographic images of test targets were reconstructed from a new, self-processing photopolymer material. A laser diode operating at 780 nm was used in the experiments. Possible effects of the polarization of the construction beams on the reconstruct

Nanocomposite materials metal/polymer combines together the properties of several components. Nowadays, they are regarded as promising systems for advanced functional applications (Armelao et al., 2006). In view of this, the incorporation of nanopart

In this article, we report a method of free-radical photopolymerization on the top end of a single-mode optical fiber. The process is very simple to carry out and uses the visible light guided in the fiber. It permits one to produce, on the fiber end

A new technological approach makes fabrication of relief computer-generated focusing elements for IR radiation by use of a dry photopolymer recording material possible. The formation of a relief structure by self-development takes place in the dark,
