Abstract

We present the design and characterization of a novel electro-optic silicon photonic 2×2 nested Mach-Zehnder switch monolithically integrated with a CMOS driver and interface logic. The photonic device uses a variable optical attenuator in order to balance the power inside the Mach-Zehnder interferometer leading to ultralow crosstalk performance. We measured a crosstalk as low as -34.5 dB, while achieving ∼2 dB insertion loss and 4 ns transient response.

摘要

我们展示了一种与CMOS驱动器和接口逻辑单片集成的新型电光硅光子2×2嵌套马赫曾德尔开关的设计与特性。该光子器件使用可变光衰减器来平衡马赫曾德尔干涉仪内部的功率，从而实现超低串扰性能。我们测得的串扰低至-34.5 dB，同时实现了约2 dB的插入损耗和4 ns的瞬态响应。
