A Novel Method for Refractive indices Measurement of Optical Waveguides
In prism-waveguide coupling experiment we found that the reflected light through the prism carried all information of waveguide refractive indices. According to the intensity variation of the reflected light, the refractive indices of optical waveguide,including effective indices of waveguide modes and substrate index, can be measured precisely. Then the refractive indices at different depths can be determined by curve fitting.
