21 April 2000Integrated switches for reconfigurable optical add-drop modules
Research and engineering are being done to incorporate polymer waveguide elements within commercial-grade silica planar-lightwave circuits to enable robust thermo-optic switches and programmable attenuators as integrable components. One of the key targets for this phase of the technology is a fully-integrated, fully-reconfigurable optical add-drop module, wherein the optical dense wavelength-division multiplexers are silica arrayed- waveguide gratings with polymer thermo-optic switches and add-drop waveguide channels interposed on the same substrate for a monolithic module.
