A Review of Polarization Dependence Applications for Asymmetric Waveguides Vertical Couplers in Compound Semiconductor Indium Phosphide
Figure 8
Effective index of the upper and the lower waveguides, for TE and TM polarizations, when the upper waveguide width is changed. The top waveguide width has a core index of 3.50 and thickness of 0.6 μm. The lower core material index is assumed to be 3.42, with a thickness of 0.7 μm. The spacer thickness is 0.3 μm.
