| Research Abstract |
In this project, we proposed a special in-phase/quadrature (IQ) modulator. Through the collaboration with Sumitomo Osaka Cement (SOC), the special IQ modulator was successfully fabricated. Based on this special IQ modulator, we proposed and experimentally demonstrated several schemes for generating advanced optical modulation formats, including: (1) optical 8PSK transmitter based on rectangular QPSK; (2) flexible 8-ary transmitter for generating 8PSK and 8QAM; (3) flexible high-order QAM transmitter for synthesizing 16QAM, 32(36)QAM, and 64QAM. We have published 10 refereed international conference papers, including top-tier conferences like OFC and CLEO, and 2 refereed papers in top-tier international journals (OSA Optics Express).
