Abstract

The box-like optical filter is one of the most important key optical switching components in the dense-wavelength division-multiplexing (DWDM) fiber-optic communication system and the intelligent optical network. The integrated high-order silicon microring resonators (MRRs) are one of the best candidates to achieve the box-like filtering spectrum response. In general, the spectrum response rectangular degree of the single MRR is very low, so that it can not be used in the DWDM system. Using the race-track high order MRRs, the bandwidth of flat-top pass band, the out-of-band rejection degree and the roll-off coefficient of the edge will be improved obviously. In this paper, a box-like optical filter based on the race-track high order MRRs with uniform couplers is presented and demonstrated. Using 15 coupled racetrack MRRs with 10 μm radius, the 3 dB flat-top pass band of 2 nm, the out-of-band rejection ratio of 30 dB and the rising and falling edges of 48 dB/nm are realized successfully.
