Cylindrically polarized X-waves paper of the week!

Journal of Optics elects the paper on cylindrically polarized X-waves, a new class of propagation invariant ultrashort light pulses with radial or azymuthal polarization as Paper of the Week.

Marco Ornigotti, Claudio Conti, and Alexander Szameit extend to the polychromatic domain the light beams with cylindrical polarization, which have widespread applications in microscopy and spectroscopy.

These light pulses represent a fully vectorial solution of Maxwell equations, can be focused at the sub-wavelength scale and may open a number of possibilities for a new generation of imaging devices, and for free space information transmission.

The paper was published in Journal of Optics (ArXiv:1602.03317)

The Quest for Quantum Gravity in Optics

Quantum gravity challenges inspire a great variety of scientists, and photonics is opening several interesting and related directions.

In a paper posted in the ArXiv, Maria Chiara Braidotti, Ziad Musslimani and Claudio Conti show the way the generalized uncertainty principle, introduced for studying physics at the Planck scale, has a role in optics, and may stimulate unexpected applications for high resolution imaging and ultrafast propagation.

The picture below shows a representation of the generalized uncertainty principle (G-UP) and the difference with the standard Heisenberg principle (H-UP), further details in our paper in the ArXiv.
