Evanescent Optics Inc. Information

Established 1975, manufacturing polarization preserving fiber optic evanescent wave devices for communications and sensor applications, including splice free arrays, interferometers, custom assemblies, precision mechanical assemblies and electronic control systems. The evanescent wave technology essentially pioneered at Stanford by Professor Shaw et. al. was built on and expanded by the development and patenting of a method for optical contact of polished fibers. This allowed the assembly of couplers without any interleaving layer of index matching adhesive or oil and resulted in the high quality devices currently manufactured. Splice free arrays and interferometers can be fabricated as coupler halves and can be made on a continuous length of fiber. Development and manufacturing of fiber optic components and fiber optic sensors has been ongoing since the early 1980's, resulting in the range of polarization maintaining and polarization preserving devices listed in the products section of www.cirl.com Custom precision mechanical devices and electronic control systems are also a significant part of company history and current work. Examples of Development Activities are included in www.cirl.com
