摘要
本文运用有效折射率法把脊形波导化成等效二维平板波导后,再运用微分法求出弱吸收情况下波导模的吸收损耗,其方法简便,精确度高.
After transforming the ridge waveguide into an equivalent slab waveguide by means of the effective index method, we have derived the expression of mode absorptive loss coefficient using the differentiation method. Based on. thes method, the optical characteristies of the ridge weak absorptive dielectric waveguide can be easily analysed and calculated with high accuracy.
