Abstract
A novel lattice structure for the design of two-port optical interleavers is presented. With the proposed lattice structure, the exact linear-phase characteristics of the two outputs of interleavers are guaranteed. The desired spectral characteristics are achieved with appropriate choices of design parameters through an optimization algorithm. It is shown that the linear-phase characteristics of the proposed interleaver are retained even in the presence of design parameter variations. The simulation results verified the effectiveness of the proposed structure and design scheme.
