Prof. Han’s Broadband Transmission Network Lab. mitigated inter-dimensional interference in QAM-PIRFSK-MDPSK optical modulation by optical intensity pre-distortion. By the proposed technique, high-speed multidimensional optical transmission is possible. The results were published in Journal of Lightwave Technology.

This study was led by Joungmoon Lee (Ph.D. Candidate) as the first author and Prof. Sang-Kook Han as the corresponding author. Inho Ha and Jinwoo Park participated in this study.
