We present theoretical results of a low-loss all-optical switch based on electromagnetically induced transparency and the quantum Zeno effect in a microdisk resonator. We show that a control beam can modify the atomic absorption of the evanescent field which suppresses the cavity field buildup and alters the path of a weak signal beam. We predict more than 35 dB of switching contrast with less than 0.1 dB loss using just 2 μW of control-beam power for signal beams with less than single photon intensities inside the cavity.
我们展示了基于微盘谐振器中的电磁诱导透明和量子芝诺效应的低损耗全光开关的理论结果。我们表明，控制光束可以改变倏逝场的原子吸收，从而抑制腔场的建立并改变弱信号光束的路径。对于腔内单光子强度以下的信号光束，我们预测仅使用2 μW的控制光束功率就能实现超过35 dB的开关对比度，且损耗小于0.1 dB。
