We report the study of chromatic dispersion ripples in birefringent crystal-based optical interleavers. The simulation indicates that for a 99.8% transmittance AR coating surface, the chromatic dispersion ripples caused by the Rhomb etalon effect could be as high as ±30 ps/nm. The experimental results are in agreement with the simulation results. We also demonstrate a practical approach to eliminate the chromatic dispersion ripples to be coupled into the output collimators. The overall interleaver chromatic dispersion, of less than 15 ps/nm within the passband, is demonstrated.
