A filter using generalized MZIs for tunable residual dispersion compensation is presented. The design, the silicon photonic realization and its characterization are presented. The device can compensate up to ±180ps/nm of residual chromatic dispersion.
Many implementations of optical finite impulse response filter for signal processing applications have been realized in integrated photonics using 22 couplers. We have implemented a filter using 4 4 couplers. Such a filter is useful for the compensation of residual dispersion in a fiber optic transmission system. Silicon photonics realization using 4-port multimode interference...
