Abstract

Tunable optical sources used in dense wavelength division multiplexed (DWDM) systems, such as distributed Bragg reflector (DBR) lasers, are highly susceptible to aging-induced wavelength drift. Without the stabilizing influence of gain clamping in the tuning section, the tendency for a tunable source to drift is greater than that of a fixed wavelength source, such as a distributed feedback or electroabsorption modulated laser. Aging of tuning sections can cause a free-running tunable source to wander out of an allotted channel band or, in a severe case, to mode hop. Wavelength drift in a tunable source is mitigated by closed loop feedback, but with time, aging still distorts the multi-dimensional channel map of optimized operating conditions. Assessing the potential for a tunable source to age is essential to ensuring device and system reliability. Using a novel technique, we assess aging in an electro-absorption modulated, distributed Bragg reflector (EADBR) laser using change of Bragg wavelength as a measure of increase of non-radiative recombination.

可调谐电吸收调制分布式布拉格反射激光器的老化评估

密集波分复用(DWDM)系统中使用的可调谐光源，如分布式布拉格反射器(DBR)激光器，极易受到老化引起的波长漂移的影响。在调谐部分没有增益箝位的稳定影响时，可调谐源的漂移倾向大于固定波长源，如分布反馈或电吸收调制激光器。调优部分的老化可能导致自由运行的可调源偏离分配的信道频带，或者在严重的情况下导致模式跳。可调谐源中的波长漂移通过闭环反馈得到缓解，但随着时间的推移，老化仍然会扭曲优化工作条件下的多维信道图。评估可调源老化的潜力对于确保设备和系统的可靠性至关重要。采用一种新颖的技术，我们评估老化的电吸收调制，分布式布拉格反射器(EADBR)激光器使用布拉格波长的变化作为增加非辐射复合的量度。
