Divergence of optical vortex beams. (PubMed) - "We also studied the divergence of vortex beams, considered as the rate of change of inner or outer radius with the propagation distance (z), and found that it varies with the order in the same way as that of the inner and outer radii at z=0. These results may be useful in designing optical fibers for orbital angular momentum modes that play a crucial role in quantum communication."

Shot-noise-limited laser power stabilization for the AEI 10  m Prototype interferometer: publisher's note. (PubMed) - Opt Lett - "This note points out corrections to typographical errors in the published version of the article [Opt. Lett.42, 755 (2017)OPLEDP0146-959210.1364/OL.42.000755]."

Narrowband transparent absorbers based on ellipsoidal nanoparticles. (PubMed, Appl Opt) - "...Lett.41, 3383 (2016)OPLEDP0146-959210.1364/OL.41.003383] but, differently from this earlier version, is transparent for any electromagnetic wave whose frequency is outside the absorption spectrum. Such an absorber also exhibits excellent performance in terms of angular bandwidth and may find application in all scenarios where narrowband absorption is required, such as for light filters or digital sensors. Full-wave simulations confirming the effectiveness of the proposed absorber as well as its robustness toward geometrical defects are provided."

2 × 1D crossed strongly modulated gratings for polarization independent tunable narrowband transmission filters. (PubMed) - J Opt Soc Am A Opt Image Sci Vis - "Lett.36, 1662 (2011)OPLEDP0146-959210.1364/OL.36.001662; Opt. For the design, we resort to a clustering global optimization algorithm, used for the first time to our knowledge for grating structures. We demonstrated two filters with a quality factor of about 4000, tunable over more than 15 nm when the angle of incidence varies over a range of 4°, and with a transmittivity at resonance greater than 95% whatever the incident polarization."

Quantitative imaging of anisotropic material properties with vectorial ptychography. (PubMed, Opt Lett) - "Following the recent establishment of the formalism of vectorial ptychography [Opt. Lett.40, 5144 (2015)OPLEDP0146-959210.1364/OL.40.005144], first measurements, to the best of our knowledge, are reported in the optical range, demonstrating the capability of the proposed method to map the four parameters of the Jones matrix of an anisotropic specimen, and therefore to quantify a wide range of optical material properties, including power transmittance, optical path difference, diattenuation, retardance, and fast-axis orientation."
