Abstract
Full-scale implementation of wavelength-division multiplexing (WDM) has focused attention on optical fiber gratings, capable of multiplexing/demultiplexing of multiple wavelengths. Furukawa Electric has carried out basic R & D on optical fiber gratings, developing products for WDM systems and a variety of other applications. This paper introduces the basic theory of optical fiber gratings and describes manufacturing techniques. It also summarizes developmental results with emphasis on gratings for WDM system applications.
