【Abstract】 The beam propagation method (BPM) was used to analyse the structure of all optical waveguide switch. The switching characteristics of all optical waveguide switch based on self focusing substrate are compared with that basedon self defocusing substrate. It is indicated that the all optical switch based on self focusing substrate shows many advantages such as low switching power and digital switching feature. The waveguide parameters were optimized by BPM.更多还原
