We present a simple and effective method for the postfabrication trimming of optical microresonators. We photobleach CLD-1 chromophores to tune the resonance wavelengths of polymer microring resonator optical notch filters. A maximum wavelength shift of ~8.73 nm is observed. The resonators are fabricated with a soft-lithography molding technique and have an intrinsic Q value of 2.6 x 10^4 and a finesse of 9.3. The maximum extinction ratio of the resonator filters is ~34 dB, indicating that the critical coupling condition has been satisfied.
