Abstract
A system and methods are disclosed for a hybrid silicon-organic scalable reconfigurable optical add-drop multiplexer. An embodiment of a scalable reconfigurable optical add-drop multiplexer (ROADM) includes an optical bus for optical signals of different wavelengths, a plurality of add/drop optical waveguides, and a plurality of ring resonators, each being optically coupled to the optical bus and to one of the add/drop optical waveguides. The ring resonators are coated with an organic electro-optic cladding layer and are configured to switch wavelength selected optical signals between the optical bus and the add/drop optical waveguides in response to control voltages applied to the organic electro-optic cladding layer. The individual ring resonators of the ROADM can be independently modulated and tuned to filter specific wavelengths.
