Traditional optical frequency comb based microwave photonic filters (OFC‐based MPFs) are seriously restricted to be operated in “Nyquist zone” for varieties of spurious frequencies signals. In this article, a fairly simple and effectivemethod for spurious frequencies suppression is demonstrated. It has no effect on the filter characteristic, and enables the filter to be freely tuned. It would greatly propel theOFC‐based MPFs' practical application. (Picture: J. Liao et al. 10.1002/lpor.201300005 , pp. L34–L38, in this issue)
