Abstract
Adjustable filters formed in fibers or waveguides based on evanescent coupling, where a coupling layer is formed between a waveguide overlay and a side-polished coupling port on the fiber or waveguide. A control mechanism may be provided to adjust a property of at least one of the waveguide overlay and the coupling layer to adjust the output of the filter.
