摘要

我们已经演示了在量子阱波导中使用与子带间跃迁(ISBT)相关的交叉相位调制的无格式波长转换。该波导作为全光相位调制器，激发ISBT的tm偏振qpsk发射信号被转换为不受ISBT吸收的交叉极化te信号。

All-optical wavelength conversion of 21.4-Gb/s QPSK signals using intersubband transition in InGaAs/AlAsSb coupled double quantum wells

We have demonstrated format-free wavelength conversion using cross-phase modulation associated with intersubband transition (ISBT) in a quantum wells waveguide. The waveguide functions as an all-optical phase modulator and a TM-polarized-QPSK launched signal that excites ISBT is converted to a cross-polarized TE-signal immune to ISBT absorption.
