The design of a multi-channel (M = 5) lattice form band pass optical delay line fllter is reported. The fllter synthesis is based on the division of total transfer function into unit blocks and the circuit parameters are obtained by constrained least square method. This band pass fllter has better performance compared with the results obtained in the conventional design techniques. For a fllter of order 35, a stop band attenuation greater than 50dB is achieved. Further, the band pass fllter is introduced in a optical flber link and simulated in Optisystem software, to verify its characteristics. |
