Proposal of a Novel Design Method for Inter-Channel Crosstalk in High-Density Optical Interconnects toward Massively Parallel Co-Packaged Optics

Year: 2026

Type: conference-paper

Abstract: We proposed a novel theoretical method to evaluate transmitter and dispersion eye closure quaternary (TDECQ) under inter-channel crosstalk in high-density parallel optical waveguides. The derived analytical expression shows excellent agreement with numerical simulations and 112-Gbit/s four-level pulse amplitude modulation (PAM-4) experiments conducted on 30-μm-pitch, 8-channel polymer waveguides, providing a practical indicator for optimizing waveguide design for massively parallel co-packaged optics.
