摘要

系统分析了如何通过电光调制的方式来消除量子点纠缠光源中不同偏振模式光子之间的频率差异，并实际设计了一套泡克耳斯盒电光调制方案，通过给其加载约8 V/ns的上升沿或下降沿电压，实现了18 MHz带宽的光子频率的移动. 表明只需增大调制电压斜率，便可以有效实现GHz以上的频率移动，为未来实现确定性完美的量子点纠缠光源提供了切实可行的依据.

关键词:

Through the electro-optic modulation on photons with different polarization modes from quantum dot entanglement sources, the way to eliminate the photon frequency difference is analyzed systematically. We design an electro-optic modulation scheme with Pockels cell, to which a rising or falling voltage of 8 V·ns-1 is applied, thereby realizing a photon frequency shift with a bandwidth of 18 MHz. Simply increasing the modulation voltage slope would realize over 1 GHz frequency shift effectively, which provides a practical basis for realizing the future quantum dot entanglement sources with a perfect certainty.
