Abstract

We report the first demonstration of error-free 640 Gbit/s demultiplexing using the Kerr non-linearity of an only 5 cm long chalcogenide glass waveguide chip. Our approach exploits four-wave mixing by the instantaneous nonlinear response of chalcogenide. Excellent performance is achieved with only 2 dB average power penalty and no indication of error-floor. Characterisation of the FWM efficiency for the chalcogenide waveguide is given and confirms the good performance of the device.

摘要

我们报告了首次使用仅5厘米长的硫系玻璃波导芯片的克尔非线性实现无差错640 Gbit/s解复用的演示。我们的方法利用硫系玻璃的瞬时非线性响应进行四波混频。仅产生2 dB的平均功率代价且无误码平台迹象，从而实现了优异的性能。给出了硫系波导的四波混频效率表征，并证实了该器件的良好性能。
