用于整个电信C波段频谱的频率转换的集成光学器件

An integrated optical device for frequency conversion across the full telecom C-band spectrum

Paul Fisher, Matteo Villa, Francesco Lenzini, Mirko Lobino

摘要:

通过光纤的高密度通信是通过波分复用技术实现的,波分复用技术是以不同的光频率同时传输许多离散信号。使用该方案可以在没有干扰的情况下传输大量数据,但是这些信号的灵活路由需要电子中间步骤,从而带来延迟成本。我们提出了一种技术,频率转换在整个WDM频谱与一个单一的设备,它消除了这种延迟成本。使用锂的光波导和两个红外泵浦光束,我们展示了如何最大限度地提高任意频率之间的转换效率,通过分析级联的非线性过程中的色散的作用。该技术被概括地提出,并且可以应用于任何合适的非线性材料或平台,以及经典或量子光学信号。

英文摘要:

High-density communication through optical fiber is made possible by Wavelength Division Multiplexing, which is the simultaneous transmission of many discrete signals at different optical frequencies. Vast quantities of data may be transmitted without interference using this scheme but flexible routing of these signals requires an electronic middle step, carrying a cost in latency. We present a technique for frequency conversion across the entire WDM spectrum with a single device, which removes this latency cost. Using an optical waveguide in lithium niobate and two infrared pump beams, we show how to maximize conversion efficiency between arbitrary frequencies by analyzing the role of dispersion in cascaded nonlinear processes. The technique is presented generally and may be applied to any suitable nonlinear material or platform, and to classical or quantum optical signals.
