Abstract

We examine the influence of doping profile optimization on the trade-off relationship between modulation bandwidth and optical loss in an InP-organic hybrid (IOH) optical modulator, comparing it with a Si-organic hybrid (SOH) optical modulator. By incorporating the RF transmission line model, which enables a more precise modulation bandwidth analysis than the RC constant model, we demonstrate that the IOH modulator can achieve a modulation bandwidth of over 500 GHz with a 2 dB loss, capitalizing on the higher electron mobility of InP. In contrast, the SOH modulator cannot attain a 200 GHz modulation bandwidth with acceptable optical loss. Furthermore, we explore the potential for further enhancing the modulation bandwidth of the IOH modulator by shortening its length, making the IOH modulator a promising candidate for future ultra-high-speed optical modulation.

带掺杂优化的 InP 有机混合光调制器带宽和光损耗的数值评估

我们研究了掺杂曲线优化对 InP 有机混合（IOH）光调制器中调制带宽和光损耗之间权衡关系的影响，并将其与 Si-organic 混合（SOH）光调制器进行了比较。与 RC 常量模型相比，射频传输线模型能实现更精确的调制带宽分析，通过采用该模型，我们证明 IOH 调制器能利用 InP 较高的电子迁移率，在 2 dB 损耗的情况下实现超过 500 GHz 的调制带宽。相比之下，SOH 调制器无法在光损耗可接受的情况下达到 200 GHz 的调制带宽。此外，我们还探讨了通过缩短 IOH 调制器的长度来进一步提高其调制带宽的潜力，从而使 IOH 调制器成为未来超高速光调制的理想候选器件。
