Original Abstract Submitted
embodiments herein describe an electro-optic waveguide having a multi-mode multi-pass phase shifter (mmps) tuner, one or more two-mode bragg gratings, and one or more selective evanescent couplers. an input signal having a fundamental mode is reflected by the one or more bragg gratings and tuned by the mmps tuner. in this manner, the electro-optic waveguide isolates the higher order modes of the input signal. the one or more selective evanescent couplers capture an output signal having the highest order mode and reduces the mode of the output signal to the fundamental mode.
