Interferometric Writing

By actively controlling the period of the fringe pattern basically any type of FBG can be generated. Grating characteristics such as wavelength range, reflection and dispersion compensation characteristics are easily controlled via the exposure SW.

Proximion’s unique technology is used in a variety of dispersion compensation products like continuous and channelized fixed dispersion compensating modules (DCMs) or tunable dispersion compensator modules (TDCMs). The technology is also used in Proximion ́s Optical Layer Monitor (OLM) product WISTOM™ and customized special products.
