Abstract

Directly modulated fiber-optic links offers significant advantages in system cost and complexity. However, they often suffer from high link loss and inferior RF performance compared with externally modulated links. In this paper, we have experimentally investigated the amplitude modulation (AM) efficiency, modulation bandwidth, and the nonlinear distortions of a directly-modulated gain-lever distributed Bragg reflector (DBR) laser under external light injection for the first time. By combining gain-lever modulation with optical injection locking, increased modulation efficiency (10 dB) and bandwidth (3 times) as well as suppressed third-order intermodulation distortion (15 dB) have been achieved simultaneously.

具有增强射频性能的光注入锁定增益杠杆分布式布拉格反射器激光器

直接调制光纤链路在系统成本和复杂性方面具有显著的优势。然而，与外部调制链路相比，它们往往存在高链路损耗和较差的射频性能。本文首次通过实验研究了外源光注入下直接调制增益杠杆分布式布拉格反射器(DBR)激光器的调幅效率、调制带宽和非线性畸变。通过结合增益杠杆调制和光注入锁定，提高了调制效率(10 dB)和带宽(3倍)，同时抑制了三阶互调失真(15 dB)。
