The low-dimensional nonlinear optical materials can provide a cost-effective and feasible way to realize the broadband optoelectronic devices. Here, we investigated the broadband nonlinear optical absorption of antimony thin film, and fabricated a broadband passive photonic diode with antimony thin film to achieve the all-optical nonreciprocal function with optical nonreciprocity factor about 5 dB at 780 nm and 2 dB at 1560 nm, respectively. The experimental results show the potential applications of antimony-based materials in broadband passive photonic diodes, and may make inroads for the cost-effective and reliable broadband optoelectronic devices.

在锑薄膜中具有饱和吸收的宽带无源光子二极管

低维非线性光学材料为实现宽带光电器件提供了一种经济有效且可行的途径。在这里，我们研究了锑薄膜的宽带非线性光吸收，并制造了一种带有锑薄膜的宽带无源光子二极管，以实现全光非互易函数，其光学非互易因子在 780 nm 处约为 5 dB，在 1560 nm 处约为 2 dB，分别。实验结果显示了锑基材料在宽带无源光子二极管中的潜在应用，并可能为低成本和可靠的宽带光电器件打下基础。
