集成光子芯片的可重构性在当前线性光学量子计算领域的实验中起着关键作用。我们展示了一种可重构的多端口干涉仪，实现为飞秒激光写入集成光子器件。该装置包括一个飞秒激光写入的4 × 4多端口干涉仪，配备12个热光学移相器，使其成为通用可编程线性光学电路。我们实现了单嵌套Mach-Zender干涉仪的快速开关时间约为10 ms，并定量分析了光学电路的可重构性。我们相信我们的结果将改善利用飞秒激光写入光子电路的量子光学实验的现状。
The reconfigurability of integrated photonic chips plays a key role in current experiments in the area of linear-optical quantum computing. We demonstrate a reconfigurable multiport interferometer implemented as a femtosecond-laser-written integrated photonic device. The device includes a femtosecond-laser-written 4 x 4 multiport interferometer equipped with 12 thermo-optical phase shifters, making it a universal programmable linear-optical circuit. We achieve a fast switching time for a single nested Mach-Zender interferometer of similar to 10 ms and quantitatively analyse the reconfigurability of the optical circuit. We believe that our results will improve the current state of quantum-optical experiments utilizing femtosecond-laser-written photonic circuits.
