Reconfigurable Integrated Microwave Photonics for Manufacturable Silicon-based Optoelectronic Chips
Abstract
A three-year basic research program is proposed to answer key science questions aboutmicrowave/mmW photonic integrated circuits (MPICs) and microwave electronic-photonicintegrated circuits (MEPICs) mostly based upon silicon. Four “manufacturable” transistor-relatedtechnology platforms for higher performance components will be investigated. Most work willbe done on the 2-mm SiGeSn/Ge/Si platform, while the AlGaN/AlN/sapphire/Si, the C-richSiC/SiO2/Si and the Si3N4/GaAs/sapphire/Si platforms shall also be studied. Beam-steering ofmicrowave antennas shall be investigated via programmable time-delays associated with SOInanobeams and slow-light grating waveguides. Instantaneous on-chip measurement of microwave frequency using a contra-direction grating- assisted coupler shall be analyzed to yield an on-chip system without isolators. Reconfiguration of multiport MZI networks will be investigated as a means for attaining a software-defined optical core within an RF/optical chip. Tunable optical/microwave filters attained with cascaded slow-light MZIs will be studied. The thermo-optic and electro-optic filter tuning will be applied also to cross-bar routing of resonant 2×2 switches to facilitate switched N×N interconnections on the RF/optical chip.
