Two-Point Resonator-Waveguide Coupling Method for Independent Coupling Optimization at Distinct Wavelengths

Abstract

We show a two -point resonator-waveguide coupling method which allows optimizing coupling independently at distinct wavelengths. An intuitive equation is provided to predict the coupling behavior of the method and the equation is verified by experiments. (C) 2019 The Author(s) [10-point type, centred]
