摘要

提出了一种基于InGaAs量子阱微谐振器的新型电子可调谐光延迟线，用于高频射频传输。该器件利用InGaAs量子阱中电荷控制的吸收边蓝移来改变谐振器和耦合器的有效折射率，从而提供了一种产生可变时间延迟的有效方法。采用基于测量的理论模型对器件性能进行了分析。仿真结果表明，5个3 × 27 μm2级联谐振器在偏置电压<0.7 V时，连续调谐范围为7~68 ps，纹波延迟<1.5 ps，可用带宽为39.3 GHz。

Electronically Tunable Wide Band Optical Delay Line Based on InGaAs Quantum Well Microresonators

A novel electronically tunable optical delay line based on InGaAs quantum well microresonators is proposed for high frequency RF transmission. The device utilizes the charge-controlled blue shift of the absorption edge in InGaAs quantum wells to change the effective refractive indices of the resonators and couplers, therefore, provides an efficient way to produce variable time delay. A theoretical model based on measurements is used to analyze the device performance. Simulation results for five 3 × 27 μm2 cascaded resonators with bias voltages <0.7 V show a continuous tuning range of 7~68 ps, a ripple delay <1.5 ps, and a useable bandwidth of 39.3 GHz.
