This $479,925 federal Project Grant awarded by the National Science Foundation's Engineering program (CFDA 47.041) will support research into improving the performance and noise reduction of avalanche photodiodes (APDs) at the University of Virginia. The goal is to explore techniques to deterministically correlate the impact ionization events in APDs in order to reduce the inherent random noise that arises from the gain mechanism. The research will combine advanced material and transport modeling, novel semiconductor alloy growth, APD fabrication, and noise characterization to demonstrate reductions in excess noise below current theoretical limits, particularly for lower gain APDs. The findings from this 3-year project have the potential to significantly enhance the sensitivity of optical receivers across a range of commercial, military, and research applications such as imaging, communications, sensing, and quantum optics.
