Abstract

We present a new microring resonator (MRR)-based optical filter that takes advantage of the improvements that can be gained from cascading two (or more) MRR elements while physically using only one MRR element due to its unique looped-back configuration. This approach avoids the costly problem associated with dynamic control of matching (or aligning) the center-wavelengths coming from the two MRR elements. This new optical filter is a generalization of our previously reported filter (called LOBOUR) based on the Cascaded Over- and Under-coupling Resonator (COUR) architecture. Here, we compare the performance of our filter to four different configurations under the following criteria: (1) lower group delay (GD), and (2) simplified solution to wavelength-drift problem, (3) lower power consumption, (4) narrower linewidth, and (5) better extinction ratio (ER).
