提出并演示了一种具有大跳波范围的全光波长转换器。该转换器由多级级联波长转换器组成，每个级联波长转换器使用不同增益带的半导体光放大器。每个级联波长转换器使我们能够执行非反转（NIV）和反转（IV）操作。根据静态特性作为转换器输入/输出功率的函数，比较了NIV和IV操作下的转换性能。虽然在两种操作中都获得了良好的转换性能，但IV波长转换具有更好的级联性，可以为级联方案获得高质量的转换信号。此外，通过重复IV波长转换证明了信号幅度再生。最后，我们首次成功地演示了超宽带波长转换，包括使用三级级联波长转换器将超过300 nm的波长跳变到更短的波长侧
An all-optical wavelength converter with a large wavelength hopping range is proposed and demonstrated. This converter consists of multistage cascaded wavelength converters using semiconductor optical amplifiers each with different gain band. Each of the cascaded wavelength converters enables us to perform both noninverted (NIV) and inverted (IV) operations. Conversion performance is compared at NIV and IV operations in terms of static characteristics as a function of input/output power of the converter. While good conversion performances are achieved at both operations, the IV wavelength conversion has better cascadability to obtain a high-quality converted signal for the cascaded scheme. Moreover, signal amplitude regeneration is demonstrated by repeating the IV wavelength conversion. Finally, we successfully demonstrate, for the first time, ultrawideband wavelength conversion, including over 300-nm wavelength hopping to the shorter wavelength side with a triple-stage cascaded wavelength converter
