Abstract: In this paper, ultrahigh-Q factor racetrack microring resonators (MRRs) are demonstrated based on silica planar lightwave circuits (PLCs) platform. A loaded ultrahigh-Q factor Q(load) of 1.83 x 10(6) is obtained. The MRRs are packaged with fiber-to-fiber loss of similar to 5 dB. A notch depth of 3 dB and similar to 37 pm FSR are observed. These MRRs show great potential in optical communications as filters. Moreover, the devices are suitable used in monolithic integration and hybrid integration with other devices, especially in external cavity lasers (ECLs) to realize ultranarrow linewidths.
