| Abstract(in English) | A novel numerical analysis of optical waveguide transitions are discussed using the Fourier series expansion method. In this approach, an artificial periodicity in the transverse direction is introduced and a continuous transition is approximated by a series of abrupt step transitions. The refractive index and modal field distributions in any uniform section can be expanded using the Fourier series with the same fundamental period. The boundary conditions at each step transition are matched by equating the respective Fourier coefficients of modal field in both sides of the step. The numerical results for a waveguide bend, a tapered waveguide, and X and Y branching waveguides show that the method is an efficient numerical approach for various waveguide transitions. |
