【Abstract】 A discrete model of Guassian beam is established based on Fourier Optics principles. The transfer efficiency of dual bending waveguide is obtained by using this model. The results show that the transfer efficiency is much higher when polarization direction of injected laser coincides with the direction of long axis than with that of short axis of the waveguide. Futher more, it offers a theorical base for dual bending waveguide′s application.更多还原
