Results
Correcting signal degradation in the electronic layer (the transimpedance amplifier, TIA) made it possible to confidently send the design to the CMOS fab — with the component and the full 100G link, over 500 m of single-mode SMF fiber, confirmed to work correctly.
Software used
Dlaczego to narzędzie. Integrated-photonics components (couplers, waveguides) are designed in OptiFDTD, while the behavior of the entire 400G link — the O/E/O budget, BER — is handled in OptiSystem. A complete path from component to system catches errors before costly fab production.
