Analysis of Y Branch Switch Based on Total Internal Reflection of Multimodes Waveguide
The reason that multimode waveguide of total internal reflection (TIR) based Y-branch switch has less cross-talk and less loss are analyzed by utilizing waveguide theory. A physical model of TIR is given and an approximate calculation method of improved TIR Y-branch switch is obtained. Simulation shows that the cross-talk and loss of the multimode waveguide of TIR Y-branch switch decrease by 15.5 dB and 0.65 dB respectively.
