Article Synopsis
  • The study explores the use of nano-hole array photonic crystal structures in Ge-on-Si single photon avalanche diodes (SPADs) to enhance their performance, specifically focusing on single photon detection efficiencies (SPDE).
  • It highlights the need for research into the effects of these structures on SPDE and dark count rates, establishing a platform for optimization and analysis of photonic crystals within SPAD devices.
  • Simulations indicate that optimized photonic crystal designs could significantly boost photon absorption to 37.09% at 1550 nm, potentially resulting in over 2.4 times higher SPDE and improved noise-equivalent power if surfaces are well-passivated.
