Abstract

A practical all-optical linearization scheme for a Mach-Zehnder modulator (MZM) for use within Microwave Photonic systems is proposed and demonstrated. It utilizes the complimentary output of a 2-output MZM to create a linearized transmitter. The concept is validated using fiber interconnected discrete components, achieving record linearity for a nonamplified link, with spurious free dynamic range (SFDR) of 118.5 dB.Hz2/3 for a single fiber system. This novel linearization scheme can be easily incorporated into photonic integrated circuits, such as on the Silicon Photonics platform with heterogeneous III–V integration, enabling high-performance, high-volume, low-cost systems.
微波光子应用的线性马赫-曾德尔调制器
提出并演示了一种用于微波光子系统的马赫-曾德尔调制器(MZM)的实用全光线性化方案。它利用2输出MZM的互补输出来创建一个线性化的发射器。使用光纤互连的离散元件验证了该概念,实现了非放大链路的创纪录线性度,无杂散动态范围(SFDR)为118.5 dB。Hz2/3用于单光纤系统。这种新颖的线性化方案可以很容易地集成到光子集成电路中,例如在具有异构III-V集成的硅光子平台上,实现高性能,大批量,低成本的系统。
