Abstract
Organic materials for optical use especially for optical fiber communication systems are described.
Plastic optical fibers which are made through closed polymerization and fiber drawing apparatus are discussed. Deuterated poly-methyl methacrylate core optical fiber whose attenuation loss is 20 dB/km at 660 nm is explained.
Light focusing plastic rods made by two step copolymerization technique or photo copolymerization technique are reviewed. Polymer optical waveguides such as dividers and star couplers using selective photo polymerization whose attenuation loss is 0.19 dB/cm at 0.83 μm are also described. Optical switches using liquid crystal as a cladding are explained and revealed to be effective to make 6 × 6 waveguide optical switches.
Finally, nonlinear optical materials are described. Organic crystals such as p-nitro aniline are discussed and it is shown that hybridization with organic salts or inclusion complexes is effective to improve second order nonlinear optical effects.
