Description: We propose to expand Nexus proprietary heterogeneous SiN based platform to include spectroscopy-grade lasers and PICs operating around Sr relevant wavelength in a wafer-scale process.

Benefits: Advanced heterogeneous integration enables maximum improvement in size, weight, and power (SWaP) and cost reduction while improving the performance of science instruments, subsystems, and components utilizing visible optical sources. PIC technologies are particularly critical for enabling small spacecraft platforms, rovers, and wearable/handheld technology for astronauts as complex photonic functionality can be integrated into a chip.

The proposed platform is applicable to multiple market verticals including augmented reality/virtual reality, healthcare, and sensing enabling us to leverage all these markets to push for commercialization while supporting NASA programmatic needs
