Paper Abstract

In this paper, we demonstrate a compact 8x8 λ-router using multimode-interference (MMI) crossing based on the microring resonator. The 8x8 λ-router was designed and fabricated with a CMOS compatible silicon on insulator technology. MMI is used to reduce the cross talk and the crossing losses of the device. Microrings with a nominal radius of 2.5 μm and small variations of 10 nm of the nominal value allow respectively a free spectral range of 32 nm and spacing between channels of 4 nm. The experimental results are in good agreement with the modeling. The basic add drop filters of the devices exhibit losses of -2 dB and on/off contrast of the resonance of 20 dB. The total losses for one channel are about -4 dB and the imbalance between the 8 channels is lower than 2 dB.
