| Abstract: | A triplexer was fabricated based on asymmetric Y branch waveguides Cascade Multimode interference(MMI) for fiber to the home(FTTH).The simulation results of spectral response show that output optical fields are clearly.And the demultiplexing function for download 1 490 nm and 1 550 nm and multiplexing function for upload 1 310 nm were achieved.The simulation results of finited different beam propagation method (FD-BPM) show that insertion loss is less than 1.49 dB|the bandwidths of three response wavelengths meet the demand of ITU.984 completely|the isolation for 1 310 nm is more than 47 dB|the isolation for between 1 490 nm and 1 550 nm is more than 29 dB. |
| Keywords: | Fiber To The Home(FTTH) Triplexer Y-Junction Multimode Interference(MMI) Beam Propagation Method (BPM) |
