简介
A dual-mode waveguide crossing is proposed and realized for the application of on-chip multimode interconnection. The present structure is realized by two 90° crossed multimode-interference (MMI) couplers. By properly choosing the width and length of the MMI section, the self-images for both the incident TM_0 mode and the TM_1 mode could be at the center of the crossing. The characterization results for the fabricated device show that low insertion loss below ∼1.5 dB and low crosstalk below ∼−18 dB can be achieved over a large bandwidth more than 80 nm for both the TM_0 and TM_1 modes.
