摘要:

有限的增益带宽积是限制标准光放大器工作的基本品质因数。在微腔设置中,由于器件的窄带宽,这成为一个严重的问题。在这里,我们介绍了一个新的设计范例的基础上例外点,放宽这一限制,并允许建立新一代的光放大器,表现出更好的增益带宽缩放关系。重要的是,我们的结果可以扩展到其他物理系统,如声学和微波。

英文摘要:

The finite gain-bandwidth product is a fundamental figure of merit that restricts the operation of standard optical amplifiers. In microcavity setups, this becomes a serious problem due to the narrow bandwidth of the device. Here we introduce a new design paradigm based on exceptional points, that relaxes this limitation and allows for building a new generation of optical amplifiers that exhibits better gain-bandwidth scaling relations. Importantly, our results can be extended to other physical systems such as acoustics and microwaves.
