Abstract

Foster-Miller is developing a family of low cost active WDM components based on electronically switchable Bragg gratings (ESBG) in holographically polymerized polymer dispersed liquid crystal. These provide approximately 50 microsecond(s) switching speeds, adequate for many network reconfiguration functions.Space switches, wavelength selective add-drop multiplexers, attenuators and switchable taps may be integrated in a variety of architectures on chip by using ESBGs with different periods and device geometries. ESBG fabrication is a one step, low cost process compatible with standard silicon optical waveguide techniques.
