Waveguide-Integrated Superconducting SNSPD PIC Model

Underwrite 100nm Niobium Nitride (NbN) superconducting nanowire single-photon detectors (SNSPDs) fabricated directly on silicon nitride optical waveguides (achieving 98% quantum detection efficiency with sub-10 picosecond timing jitter for quantum key distribution). Model quantum computing photonic module sales ($18,500/module), and 15-yr IRR.
