Abstract

We demonstrate the 4-stage and 8-stage silicon traveling-wave photodetectors (TWPDs) with inductive gain peaking technique. Compared with un-peaked TWPDs, the bandwidths of 4-stage and 8-stage TWPDs integrated with inductors are improved from 32 GHz to 44 GHz, and from 16GHz to 24 GHz, respectively. It is experimentally validated that gain peaking is an effective technology to improve bandwidths for multiple-stage TWPDs.
