It then describes the design of the three main components, namely the rib waveguide structure, the TE/TM mode convertor using four electrodes per period, and the TE/TM mode splitter with gold deposit on the decoupling branch. Results of operation simulation calculations are given.engallium arsenidegallium compoundsiii-v semiconductorsindium compoundsintegrated opticsoptical communication equipmentoptical switchesoptical waveguide componentsreceiverssemiconductorstransmission capacitysingle-mode optical fibreoptical polarization-diversity receiverrib waveguide structurete/tm mode convertorte/tm mode splitteroperation simulationinpGaInAsP-InP technologyau deposit621conference paper
