由光功率流引起的对称光波导TE模的变化

摘要

An asymmetric optical waveguide configuration is shown in Fig.1 where n_(20)>n_3>n_1.For TE modes,(?)(x)=(0,E_y(x),0).We assumelight-wave propagates along the Z-axis.If thenonlinear effect is neglected for the time being,thenn_d=0.For n_1=1.000,n_(20)=2.300,n_3=2.200,d=5.0μm,λ=1.06μm,five TE modes can be ob-
