摘要

为实现多通道片上信号传输，设计一种多模硅光集成器件（PIC），包括一对10通道片上模式多路复用-解复用器以及具有超小弯曲半径的总线波导。选择多模总线波导宽度使其能支持10种模式，其中包括4种横磁（TM）和6种横电（TE）偏振模式。多模总线波导由基于修正的欧拉曲线超小弯曲半径组成。实验结果表明，即使组成总线波导的弯曲半径仅为40µm，该芯片仍可在大带宽1520−1610 nm上实现10通道传输，且具有约−20 dB的低模间串扰。与传统弯曲半径相同的圆弧弯曲相比，该集成器件有明显优势。

Abstract

A multimode silicon photonic integrated circuit (PIC) comprising a pair of on-chip mode (de)multiplexers with 10-mode channels and a multimode bus waveguide with sharp bends is demonstrated to enable multi-channel on-chip transmissions. The core width of the multimode bus waveguide is chosen such that it can support 10 guided modes

of which there are four transverse-magnetic polarization modes and six transverse-electric polarization modes. This multimode bus waveguide comprises sharp bends based on modified Euler curves. Experimental results demonstrate that the present silicon PIC enables the 10-channel on-chip transmission with a low inter-mode crosstalk of approximately 20 dB over a broad bandwidth of 1520–1610 nm even when the bending radius of the S-bend is as small as 40 μm. Compared with a silicon PIC using a conventional arc-bend with the same bending radius

our proposed PIC demonstrates a significant improvement.
