Photopolymer holographic recording material
Optik, 2001Summary Photopolymers are promising materials for use in holography. They have many advantages, such as ease of preparation, and are capable of efficiencies of up to 100%. A disadvantage of these materials is their inability to record high spatial frequency gratings when compared to other materials such as dichromated gelatin and silver halide ...

Holographic analysis of photopolymers
SPIE Proceedings, 2017Two-beam holographic exposure and subsequent monitoring of the time-dependent first-order Bragg diffraction is a common method for investigating the refractive index response of holographic photopolymers for a range of input writing conditions. The experimental set up is straightforward, and Kogelnik’s well-known coupled wave theory (CWT)[1] can be ...

Functionalized Photopolymers for Integrated Optical Components
Molecular Crystals and Liquid Crystals, 2006ABSTRACT Photopolymeric matrices functionalized with optically active molecules are of special interest to elaborate low cost organic components for use in integrated optics. We have first studied the patterning of the optical properties using appropriate masks for the actinic light inducing the polymerization through a one-photon absorption process ...

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

Multi-Layer Photopolymer Micromachining
MRS Proceedings, 2005AbstractThis paper presents a novel method to create and integrate micro-machined devices and high aspect-ratio (height-to-width ratio) microstructures in which the microstructures are built up using multiple layers of photopolymer film and/or viscous solution. Very high aspect-ratio 2-and 3-dimensional (2-D and 3-D) microstructures were constructed by

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 ...

Holographic Recording with Photopolymers*
Journal of the Optical Society of America, 1970Phase holograms have been recorded using several photopolymers. These photopolymer recording systems are self-developing and require only uv-light fixing. Sensitivities as high as 0.6 mJ/cm2 have been achieved with He–Ne–laser light. Reconstructions from 3000-line/mm gratings recorded on these materials have been achieved; however, the signal-to-noise ...

In late 1960’s and early 1970’s there has been a great interest among researchers in photopolymer material as new entrant for holographic recording media possessing very high resolution. Daring this period many research articles were published by several authors(1–4) exhibiting unusual behaviour of these materials. But they ended up with its nonbinding
