Parametric oscillation in vertical triple microcavities

Article Abstract:

Optical parametric oscillation is a nonlinear process that enables coherent generation of signal and idler waves, shifted in frequency from the pump wave. Efficient parametric conversion is the paradigm for the generation of twin or entangled photons for quantum optics applications such as quantum cryptography, or for the generation of new frequencies in spectral domains not accessible by existing devices.

Redistribution of energy available for ocean mixing by long-range propagation of internal waves

Article Abstract:

Computations of horizontal internal-wave propagation from 60 historical moorings are described and relating them to the source terms of internal waves computed previously. The analysis of near-inertial frequencies and semidiurnal tidal frequencies suggested significant effect on the space-time distribution of energy availability for global mixing.

Beyond diffraction

Article Abstract:

Researchers show that hyperlens can turn evanescent fields into propagating waves, producing magnified far-field images of sub-wavelength structures. These novel imaging devices find numerous applications in optical imaging.
