我们展示了基于交叉相位调制的碳纳米管（CNTs）沉积的D形光纤中的非线性偏振旋转的宽调谐波长转换。一个5厘米长的碳纳米管沉积的D形光纤被用作10 Gb/s的非归零信号的波长转换的非线性介质。在误码率测试中，获得了波长超过40 nm的可调谐转换信号，功率损失约为2.5dB。
We demonstrate widely tunable wavelength conversion based on cross-phase modulation induced nonlinear polarization rotation in a carbon nanotubes (CNTs) deposited D-shaped fiber. A 5-centimeter-long CNT-deposited D-shaped fiber is used as the nonlinear medium for wavelength conversion of a 10 Gb/s non-return-to-zero signal. Wavelength tunable converted signal over 40 nm is obtained with around 2.5-dB power penalty in the bit-error-rate measurements.
