摘要

The fundamental crosstalk characteristics related to design of highly compact optical and RF signal lines has been studied in this work. The systematic investigation of the crosstalk of parallel waveguides are carried out by modal analysis and the beam propagation analysis. The new idea of crosstalk mitigation in PIC by using uniform air gap along the longitudinal structure has been proposed. The crosstalk mitigation up to − 40dB by using air gap can successfully achieve, which results in reduction of spacing between signal lines.
