介绍了一种新型光调制器--衰减全内反射调制器（ATRM）的调制效率和带宽限制。ATRM基于将光束耦合到表面等离子体波，并且其制造与GaAs集成电路技术兼容。我们演示了调制到22 GHz（外推的1.5 dB光调制带宽为26 GHz），并表明可以使用现有材料构建具有高调制指数的器件。
The modulation efficiency and bandwidth limitations of a new type of light modulator, the attenuated total internal reflection modulator (ATRM), are described. The ATRM is based on coupling a light beam to a surface plasmon wave, and its fabrication is compatible with GaAs integrated circuit technology. We demonstrate modulation to 22 GHz (the extrapolated 1.5 dB optical modulation bandwidth is 26 GHz) and show that devices with high modulation index can be built using existing materials.
