We propose to improve, refine and mature Nexus proprietary heterogeneous SiN based platform to improve the short-wavelength propagation losses, and integrate high-responsivity/high-quantum efficiency photodetectors in visible in a wafer-scale process for NASA needs and infusion into existing and upcoming instruments. Anticipated
Benefits: We are specifically addressing existing need at NASA for PIC technologies: "On-chip detectors with high responsivity/quantum efficiency from 300 to 800 nm. Additionally, approaches demonstrated in, or compatible with, commercial foundries are of particular interest." The proposed platform is applicable to multiple market verticals including augmented reality/virtual reality, healthcare, quantum enabling us to leverage all these markets to push for commercialization while supporting NASA programmatic needs
