Ww. Lui et al., MODELING AND DESIGN OF BENDING WAVE-GUIDE BASED SEMICONDUCTOR POLARIZATION ROTATORS, IEEE photonics technology letters, 9(10), 1997, pp. 1379-1381
A theoretical model for bending waveguide based semiconductor polariza
tion rotators has been established, which is based on the full-vectori
al wave equations for bending waveguides and the coupled-mode theory.
Calculation results obtained using this model and measurement data are
found in good agreement.
