Abstract

Compact microring resonator devices are realized by using a small SU-8 polymer strip waveguide that has an SU-8 polymer core $(n \sim {\hbox {1.573}})$, an SiO$_{2}$ buffer $(n \sim {\hbox {1.445}}),$ and an air cladding. Due to the high index contrast of the optical waveguide, a small bending radius (${\sim} {\hbox {150}}\ \mu$m) is used for the MRR. To enhance the coupling between the access optical waveguides and the microring, 2$\,\times\,$2 multimode interference couplers are used. The measured spectral response of the through port shows a high extinction ratio of over 15 dB and a 3-dB bandwidth of about 0.38nm (corresponding to a moderate $Q$-value of ${\sim} {\hbox {4500}}$).
