Plasmonic addressing structure
No full textWe present here a new structure allowing for independent addressing of sub-micrometric area. Plasmonic chains are deposited above a waveguide array. The coupling between the chains and the waveguides is numerically analyzed. This structure could have applications in various domains, from holography with reconfigurable metasurfaces to biotechnology with lab-on-chip structure
Case comment: R (Wang Yam) v Central Criminal Court
No full textIn R (Wang Yam) v Central Criminal Court the Supreme Court has held that the domestic courts enjoy an inherent jurisdiction to make orders which have the effect of preventing an applicant to the Court of Human Rights from putting material before that court. This analysis considers the decision in the context of the growth of ‘secret trials’ in the domestic criminal system, arguing that the Supreme Court’s decision may merely postpone a dispute between the UK and the Strasbourg Court on the implications of this growth in secrecy for the UK’s compliance with the Convention

Integrated plasmonic tweezer for linear repositioning of nanometric objects
No full textPlasmonic nanoparticles chains coupled to traditional SOI waveguides allow for nanoobjects trapping and jumpless linear repositioning. This innovative feature is here numerically detailed. This may be extremely captivating for the conception of integrated optomechanical nanoactuators
All-Optically Addressable Sub-Micron Pixels
No full textSpatial light modulators need smaller pixels to achieve high resolution holographic displays. Today, Liquid-Crystal on Silicon (LCOS) technology does not allow downsizing pixel pitch below 1 μm [1,2] and metasurface technology still does not enable an independent control of each meta-atom in the visible [3,4]. To this end, it is necessary to be able to independently address several pixels with a pixel pitch under 1 μm
Optical isolators based on magnetoplasmonic subwavelength gratings
No full textOptical isolators are one-way devices allowing light to pass only in one direction. They are elementary components to protect laser diodes against spurious back reflections or to build functions like optical circulators. Here we propose a metal-dielectric non-reciprocal waveguide that may pave the way toward the conception of compact integrated isolators. The challenge is to design integrated optical isolator with low footprint, high isolation ratio and low insertion losses. Fig. 1(a) depicts a 3D sketch of the proposed structure which includes a one dimensional (1D) subwavelength periodic gold plasmonic grating. The latter is located on one side of a magneto-optical (MO) dielectric Bismuth Iron Garnet (BIG) waveguide. These elements are placed on top of a non-MO Gallium Gadolinium Garnet (GGG) substrate and buried in SiO2 superstrate. In this configuration nonreciprocal transmission of the TE fundamental mode is obtained by applying a vertical static magnetic field (inducing vertical magnetization in BIG layer)
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
