We demonstrate a novel on-chip two-mode division multiplexing circuit using a tapered directional coupler-based TE(0)&TE(1) mode multiplexer and demultiplexer on the silicon-on-insulator platform. A low insertion loss (0.3 dB), low mode crosstalk (< -16 dB), wide bandwidth (~100 nm), and large fabrication tolerance (20 nm) are measured. An on-chip mode multiplexing experiment is carried out on the fabricated circuit with non return-to-zero (NRZ) on-off keying (OOK) signals at 40 Gbit/s. The experimental results show clear eye diagrams and moderate power penalty for both TE(0) and TE(1) modes.
我们展示了一种新颖的片上双模分频复用电路，该电路在绝缘体上硅平台上使用基于锥形定向耦合器的TE(0)和TE(1)模式复用器和解复用器。测量得到低插入损耗（0.3 dB）、低模式串扰（< -16 dB）、宽带宽（~100 nm）和大制造容差（20 nm）。在制造的电路上，对40 Gbit/s的非归零（NRZ）开关键控（OOK）信号进行了片上模式复用实验。实验结果显示，TE(0)和TE(1)模式均有清晰的眼图和适度的功率代价。
