SIMPLE METHOD FOR ESTIMATING MINIMUM BEND RADII OF SOI SINGLE MODE CURVED RIB WAVEGUIDES
【摘要】 采用有效折射率方法计算了 SOI弯曲波导由于辐射损耗引起模式截止的最小弯曲半径 ,得到了一个估算弯曲波导的最小弯曲半径的解析表达式
【Abstract】 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.
