摘要

我们提出了一种实现双调谐马赫-曾德尔干涉仪光子开关中两个热光移相器粗-精控制的新方法。我们在一个制造的硅开关中演示了这一概念，该开关包含由相同的单片集成低分辨率数模转换器驱动的热光相位调谐器。

Coarse-Fine Control of Dual-Tuner Mach-Zehnder Interferometer using Identical Low-Resolution DACs

We present a novel approach for achieving coarse-fine control of two thermo-optic phase shifters in a dual-tuner Mach-Zehnder interferometer-based photonic switch. We demonstrate the concept in a fabricated silicon switch containing thermo-optic phase tuners driven from identical monolithically integrated low-resolution digital-to-analog converters.
