Abstract
Microresonator filters reported so far have been ah-pole-type filters. We r
eport two experimental realizations of zero-type (notch) filters using GaAs
-AlGaAs microring resonators. The first is a ring coupled to one side of a
Mach-Zehnder interferometer, the Y-branch of which has an effective splitti
ng angle of 50 degrees with 0.5-dB loss, The second is a ring whose toss ex
actly matches the coupling to the input/output waveguide with an extinction
greater than 20 dB.
