我们提出并实验证明了一种基于光机械效应的节能型光二极管。光信号在前向传播过程中可以传输，而在后向传播过程中被阻挡。在4.0mW的低功率光信号发射下，非对称硅微腔（MRR）的最大共振红移可达0.74nm，前后向非互易传输比（NTR）为12.7dB。10 dB和5 dB工作带宽分别为0.08 nm和0.24 nm。理论上可以通过改变输入功率来连续调节工作带宽。
We propose and experimentally demonstrate an energy-efficient optical diode based on the optomechanical effect. The optical signals could transmit during forward propagation while be blocked during backward propagation. When launching optical signal with a low power of 4.0 mW, the maximum resonance red-shift of the asymmetric silicon microring resonator (MRR) could be up to 0.74 nm, in this case, a forward-backward nonreciprocal transmission ratio (NTR) of 12.7 dB has been achieved. The 10-dB and 5-dB operation bandwidths are 0.08 nm and 0.24 nm, respectively. The operating bandwidth could be continuously tuned theoretically by changing the input power.
