Canadian Instrumentation & Research Ltd
CIR Ltd. was established in 1975 as an R&D group contracting in Optics and associated disciplines for Federal Government and commercial organizations. The scope of activities can be seen from the list of selected completed contracts.
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.
