主要内容:In this presentation, the principle and advances of dual parallel and in-phase and quadrature amplitude modulation (I&Q) architecture based on the dual-parallel optical multiplexing of EO phase Mach-Zehnder interferometer (DP-MZI) and microwave phase-shift (PS) frequency multiplication are described at first. Then, the illustrative important achievements of Photonic Technology Laboratory (PTL) on the amendable coherent EO circuits with silicon photonic integrated circuits (PIC) passive split/combinative technology are presented. These establishments include: (i) the systematic analysis and simulations for the characteristics of equivalent circuits of an N=4 parallel MZI based I&Q and single-side band (SSB) EO modulation architecture with the multi-mode interference (MMI) optical division technology; (ii) the theoretical analysis and modeling for MMI-PIC based optical division to realize the 8-tupled, 12-tupled and 24-tupled modulation with suppression of unwanted harmonic waves; (iii) the investigation for a quadrature polarization DP (2xDP) MZI based equivalent PIC system to enhance the high spectral efficiency of I&Q/SSB frequency multiplication; and (iv) a designed/fabricated prototype of silicon-PIC MMI-based N=8 generalized MZI modulation and the early-step experiments are shown. Finally, in this talk the speaker also reviews some significant progresses made by other in-field researchers in this world to imply the future trend and essential applications of this advanced multi-channel EO modulation area.
