We demonstrate liquid core waveguides defined by UV to enable selective water infiltration in nanoporous polymers, creating an effective refractive index shift Δn=0.13. The mode confinement and propagation loss in these waveguides are presented.

摘要

We demonstrate an averaging process, corresponding to the harmonic-mean, that average quantum noise sources better than the basic arithmetic-mean strategy. Using simple linear optics, homodyne detection and feedforward, and it is tested on squeezed states.
