Parameter Identification for the Cascaded Fiber Optic Lattice Structure using the Schur Algorithm

摘要

We propose a method based on the Schur algorithm for the identification of an Ath-order recirculating fiber-optic lattice structure. We can obtain the coupling coefficients and delay time of the Nth-order recirculating fiber-optic lattice structure using the Schur algorithm from the input and the reflected data of the overall system measured by oscilloscope. To verify the validity of proposed method, we have composed a second order recirculating fiber-optic lattice structure with the coupling coefficients 0.1 and 0.3687. We have observed that the coupling coefficients computed by the proposed algorithm match very closely to the corresponding true values.
