Holographic grating formation in photopolymers
Optics Letters, 1996We introduce a model describing real-time grating formation in holographic photopolymers, under the assumption that the diffusion of free monomers is much faster than the grating formation. This model, which combines polymerization kinetics with results from coupled-wave theory, indicates that the grating formation time depends sublinearly on the ...

Self-written waveguides in photopolymer
Applied Optics, 2018Self-written waveguide (SWW) trajectories fabricated inside a dry photopolymer bulk material, acrylamide/polyvinyl alcohol (AA/PVA), are studied. Their production using both Gaussian and Laguerre-Gauss exposing (writing) light beams, output from optical fibers, is explored. The formation of the primary and secondary eyes is also discussed. Furthermore,

Latent-imaging photopolymer systems
Applied Optics, 1978A new high-resolution latent-imaging photopolymer system is reported for recording thick refractive-index patterns such as volume phase holograms and grating devices. A photosensitive polymerization initiator is chemisorbed on the surfaces of a porous glass matrix (average pore diameter 4 nm).

Photopolymers for rapid prototyping
Journal of Coatings Technology and Research, 2007Rapid prototyping by means of stereolithography using different types of photopolymers has gained increasing interest because cellular structures can be built at a high resolution with sub-μm feature sizes. Structures made with digital light processing and microstereolithography and rapid prototyping based on two-photon absorption photopolymerization ...

Photopolymer Material for Holography
Applied Optics, 1972An experimental Du Pont holographic photopolymer material produces an index modulation in excess of 10(-2) utilizing a diffusion mechanism. Optimum exposure in air is typically 30 mJ/cm(2) , in nitrogen 3 mJ/cm(2). Composition, beam ratio, and exposure power all affect the index modulation.

Optics & Laser Technology, 1972
Photopolymers for application in holography have the advantage over silver halide emulsions that a phase hologram is formed in situ during exposure. The article describes the results of tests concerning the resolving power and photosensitivity of a combination of the monomers acryl amide and methylene-bis-acryl amide. This combination forms a copolymer

Photopolymer Materials for Holography
Holography, 1996Interest in holograms as diffractive optical elements began with the early recognition of the correspondence of transmission holograms and Fresnel zone plates.1,2 Optical designs based on holographically-generated optical elements (HOEs) and the extension of computer-based design programs to holographic gratings appeared in the late 1960s.3,4,5 Use of ...
