ABSTRACT:
Optical devices extending the free spectral range and tunability of, and enabling hitless switching of, integrated optical filters suitable for add-drop filters. Devices include (i) a splitter device configured to split an input spectrum among a plurality of output ports, and a combiner device configured to combine at least a portion of the split input spectrum into a single output port, splitter and combiner having respective first and second input and output ports, and a respective transfer matrix, the matrix of the combiner being the diagonal transpose of that of the splitter; (ii) a first optical path coupling the first output port of the splitter and the first input port of the combiner; (iii) a second optical path coupling the second output port of the splitter and the second input port of the combiner, wherein the first and second optical paths are configured to introduce, at least at a wavelength of the input spectrum, a relative phase shift of π radians; and (iv) an optical filter coupled to at least one of the first and second optical paths.
