基于量子干涉的电光波形互连
An electro-optic waveform interconnect based on quantum interference
摘要:
通过电场调制光场的能力被认为是用于光通信和信息处理系统的电光互连的关键功能。这种互连所需的主要器件之一是电光调制器(EOM)。目前基于电光效应和电吸收效应的电光调制器由于其组成材料的弱电光特性而通常体积庞大且功率效率低。在这里,我们提出了一种新的机制来产生任意波形的电光调制器的基础上的量子干涉,其中的实部和虚部的磁化率的超高效率相干工程。基于该EOM,实现了从电压到调制光吸收的波形互连。我们期望这种新型的电光互连在光通信和光网络等方面有广泛的应用。
英文摘要:
The ability to modulate an optical field via an electric field is regarded as a key function of electro-optic interconnects, which are used in optical communications and information processing systems. One of the main required devices for such interconnects is the electro-optic modulator (EOM). Current EOM based on the electro-optic effect and the electro-absorption effect often is bulky and power inefficient due to the weak electro-optic properties of its constituent materials. Here we propose a new mechanism to produce an arbitrary-waveform EOM based on the quantum interference, in which both the real and imaginary parts of the susceptibility are engineered coherently with the superhigh efficiency. Based on this EOM, a waveform interconnect from the voltage to the modulated optical absorption is realised. We expect that such a new type of electro-optic interconnect will have a broad range of applications including the optical communications and network.
