Abstract

This paper describes four different types of PLC Fourier-filter interleaver designs and compares their optical performance. All of these interleave filters consist of multiple unbalanced Mach-Zender interferometer stages, but use different directional coupler designs. They use a new optical design with good optical performance, including cross talk > 32 dB, 0.5dB passband width > 68% of channel spacing, and ripple within 40% of channel spacing window of < 0.25dB. A new filter approach is introduced which uses only standard symmetric couplers in a coupling-ratio dispersion compensating configuration and provides better optical performance in terms of crosstalk, passband width, ripple and insertion loss and better tolerance to fabrication errors as compared to interleave filter circuits that utilize MMI couplers, Fourier-filter couplers, or standard couplers in a conventional configuration.
