Toward Photon-Efficient Key Distribution over Optical Channels [PDF]
, 2014 This work considers the distribution of a secret key over an optical (bosonic) channel in the regime of high photon efficiency, i.e., when the number of secret key bits generated per detected photon is high.

Colourful 3D anti-counterfeiting label using nanoscale additive manufacturing
Virtual and Physical Prototyping, 2023 Microprinting is changing anti-counterfeit technology by producing complex micro-/nano-scale labels to increase the security level. However, the current microprinted anti-counterfeiting labels only contain 2D features, thought of as single coding (e.g ...

Label-free optical biosensing with slot-waveguides [PDF]
Optics Letters, 2008 We demonstrate label-free molecule detection by using an integrated biosensor based on a Si(3)N(4)/SiO(2) slot-waveguide microring resonator. Bovine serum albumin (BSA) and anti-BSA molecular binding events on the sensor surface are monitored through the measurement of resonant wavelength shifts with varying biomolecule concentrations.

Rational design and synthesis of SERS labels [PDF]
, 2013 SERS labels are a new class of nanotags for optical detection based on Raman scattering. Central advantages include their spectral multiplexing capacity due to the small line width of vibrational Raman bands, quantification based on spectral intensities,

TreeRipper: towards a fully automated optical tree recognition software [PDF]
, 2010 Relationships between species, genes and genomes have been printed as trees for over a century. Whilst this may have been the best format for exchanging and sharing phylogenetic hypotheses during the 20th century, the worldwide web now provides faster ...
