Abstract

Significant technological progress in wavelength conversion by difference-frequency-generation (DFG) has taken place since its conception for wavelength-division-multiplexing (WDM) network applications in 1991. This paper reviews progress in wavelength conversion by DFG in AlGaAs waveguides and discusses its implications for WDM network applications. The measured conversion efficiency versus the input wavelength is shown for two input polarizations. An extremely broad tuning curve is demonstrated with /spl sim/90 nm bandwidth and a polarization independent conversion process. Simultaneous conversion of 17 channels is also shown. Here, arbitrary input polarizations were used, and each channel achieves identical conversion efficiency. One of the important considerations for network applications is a requirement for an effective means to filter unwanted channels. One such method is based on polarization diversity, and a measured spectrum exploiting the unique polarization characteristics of the conversion process in an AlGaAs waveguide is also given.

AlGaAs波导中差频产生波长转换的研究进展

自1991年在波分复用(WDM)网络中应用差频产生技术(DFG)以来，波长转换技术取得了重大进展。本文综述了在AlGaAs波导中使用DFG进行波长转换的研究进展，并讨论了其对波分复用网络应用的意义。测量的转换效率与输入波长的关系显示为两个输入偏振。在/spl sim/ 90nm带宽下，显示了极宽的调谐曲线和与极化无关的转换过程。同时显示了17个通道的转换。在这里，任意输入极化被使用，并且每个通道获得相同的转换效率。网络应用程序的一个重要考虑因素是需要一种有效的方法来过滤不需要的信道。其中一种方法是基于偏振分集，并给出了利用AlGaAs波导中转换过程的独特偏振特性的测量光谱。
