Abstract

In this paper, the circuit models of optical to electrical(O/E) characteristics of waveguide photodiode(WGPD) submodule are examined. Test structures of WGPD and WGPD submodule were fabricated and S21 parameter was measured to characterize the O/E conversion property. Valid circuit models were derived by RF circuit simulation and O/E characteristics were modeled to analyze the effects of model parameters on the WGPD submodule performances. Based on the results, it can be concluded that the suggested WGPD submodule model can explain the characteristics of the O/E conversion of WGPD submodule, where the parasitic components originated from ribbon bonding block crucially influence on the performance of WGPD submodule, are able to show more efficient property by making compact bonding structure. We propose an effective WGPD submodule bonding structure and it can ensure the 40Gbps operation of WGPD.
