提出并制作了一种基于硅芯光纤平台的全光纤集成非线性硅光子波长转换器。硅光纤直接拼接到传统的单模光纤上，通过反向锥形纳米尖峰帮助减少不同芯材之间的模式失配。在器件长度仅为1 cm的情况下，实现了C波段选定波长的四波混频波长转换，转换效率高达-22.1db。对20-Gb/S码率的正交相移键控信号进行了成功的转换，在误码率=3.8×10(-3)时有1到2分贝的惩罚水平，证明了硅光纤器件在构建超紧凑型全光纤光信号处理系统中的适用性。
An all-fiber integrated nonlinear silicon photonic wavelength converter has been proposed and fabricated using the silicon core fiber platform. The silicon fiber was spliced directly to a conventional single mode fiber, facilitated via an inverse tapered nano-spike that helped to reduce the mode mismatch between the different core materials. Four-wave mixing-based wavelength conversion with an efficiency as high as -22.1 dB has been achieved for selected wavelengths across the C-band in a device length of only similar to 1 cm. Successful conversion of quadrature phase-shift keying signals at a 20-Gb/s bitrate, with a 1 to 2 dB penalty level at the bit error ratio (BER) = 3.8 x 10(-3), was used to demonstrate the suitability of the silicon fiber device for the construction of ultra-compact, all-fiber-based optical signal processing systems.
