Large Scale 2D Material- Active Silicon Photonics
Abstract
A. Hybrid integration scheme of 2D materials and high-speed characterization: With minimized interface dangling bonds, we demonstrated electro-static doping in graphene from foundry manufactured substrates. We modeled RC constant limitation and carrier transient limitation of the hybrid device and compared to experimental data. B. Metasurface based advanced multimode interference device on silicon photonic platform: We demonstrated the first low loss metasurface structure on silicon photonic platform, which revolutionize the photonic integrated circuits wired by single mode waveguides. We demonstrated ultra-compact mode converter, convolver and deep learning based on the diffractive optic elements based photonic integrated processors. C. Foundry manufacturing: We accomplish one passive and one active TAPEOUT to AIM photonics, with the low loss photonic design picked from the first passive TAPEOUT. The deep UV lithography generated photonic crystal device exhibit the lowest loss among all the published results. Given the fabrication quality, we are exploring new photonic crystal based PDK components, and designed ultralow loss metalens-photonic crystal cavity-metalens microsystems with 3dB total loss. D. Space test of silicon photonic devices: We accomplished radiation exposure of passive and active silicon photonic devices on near earth orbit for 6,700 orbits. We characterized the nonlinear response of microring resonators and high-speed optoelectronic response of MZI modulators before and after exposure. E. Sponsored by the grant, Gus group at University of Delaware published 47 peer reviewed conference and journal papers, including 2 publications on Nature Communication and 1 publication on npj 2D materials and applications. Gu delivered 23 invited seminars in the YIP period. The involved students and PI received numerous awards during the period (section B.3). Those works on international space station test; high speed graphene optoelectronics and integrated
