We presented an optical microring‐assisted Mach–Zehnder interferometer interleaver. With the microrings‐assisted, the optical interleaver exhibits a near‐square passband shape. The fabricated device behaves as a 1 × 2 100–200 GHz interleaver operating at 1.55 mm region. The insertion loss (fiber‐to‐fiber loss) is 1.72 dB, and the stopband extinction ratio is about 20 dB. Design and simulation results are also discussed for further improvement of its performance. The good performance makes this interleaver very attractive for future optical communication systems. © 2010 Wiley Periodicals, Inc.
