SIMPLE METHOD FOR ESTIMATING MINIMUM BEND RADII OF SOI SINGLE MODE CURVED RIB WAVEGUIDES
估算SOI单模脊形弯曲波导最小弯曲半径的简单方法

A simple method based on the effective index method was used to estimate the minimum bend radii of curved SOI waveguides. An analytical formula was obtained to estimate the minimum radius of curvature at which the mode becomes cut off due to the side radiative loss.
