Pulses of light to encrypt data and protect security of cryptocurrencies

Physorg  January 11, 2018 An international team of researchers (USA – University of Southern California, Mexico) report a new strategy to fabricate near-infrared frequency combs based on combining high-Q microcavities with monomolecular layers of highly nonlinear small molecules. The functionalized microcavities demonstrate high-efficiency parametric oscillation in the near-IR and generate primary frequency combs with 0.88-mW thresholds, improving optical parametric oscillation generation over nonfunctionalized devices by three orders of magnitude. This organic-inorganic approach enables otherwise unattainable performance and will inspire the next generation of integrated photonic device platforms… read more. Open Access TECHNICAL ARTICLE
