    1. Optical trapping and manipulation of micrometer and submicrometer particles

      Mark Daly, Marios Sergides and Síle Nic Chormaic

      Manipulating particles using light alone has proven to be an indispensable tool with significant effort being made to create stable traps for submicron particles. Optical trapping is a highly diverse field and borrows techniques from many areas of optics in order to extend the limits of optical manipulation. This review covers some of the early work on optical trapping, while focusing on more recent developments related to submicron particle trapping.

    1. Hybrid vertical-cavity laser with lateral emission into a silicon waveguide

      Gyeong Cheol Park, Weiqi Xue, Alireza Taghizadeh, Elizaveta Semenova, Kresten Yvind, Jesper Mørk and Il-Sug Chung

      Article first published online: 10 APR 2015 | DOI: 10.1002/lpor.201400418

      A III-V-on-SOI vertical-cavity laser with lateral emission into a silicon waveguide has been demonstrated, using CMOS compatible processes. This laser has the advantages of longwavelength vertical-cavity surface-emitting lasers, such as low threshold and high side-mode suppression ratio, while allowing integration with silicon photonic circuits. It has the potential for ultrahigh-speed operation beyond 100 Gbit/s.

      Bulk plasmon-polaritons in hyperbolic nanorod metamaterial waveguides

      Nikolaos Vasilantonakis, Mazhar E. Nasir, Wayne Dickson, Gregory A. Wurtz and Anatoly V. Zayats

      Article first published online: 9 APR 2015 | DOI: 10.1002/lpor.201400457

      The waveguiding properties and mode structure of planar anisotropic metamaterial waveguides are characterized experimentally and theoretically. The extraordinary modes, originating from bulk plasmon polaritons of the metamaterial with hyperbolic dispersion, are shown to exhibit low or negative group velocity and high effective refractive indices (up to 10), allowing a deep-subwavelength-size single mode waveguides. The results are important for understanding of the enhanced nonlinear, sensing and Purcell properties of such metamaterials.

    2. Photonic Floquet topological insulators in atomic ensembles

      Yiqi Zhang, Zhenkun Wu, Milivoj R. Belić, Huaibin Zheng, Zhiguo Wang, Min Xiao and Yanpeng Zhang

      Article first published online: 7 APR 2015 | DOI: 10.1002/lpor.201400428

      The feasibility of realizing a photonic Floquet topological insulator (PFTI) in an atomic ensemble is demonstrated. The interference of three coupling fields will split energy levels periodically, to form a periodic refractive index structure with honeycomb profile that can be adjusted by different frequency detunings and intensities of the coupling fields. This in turn will affect the appearance of Dirac cones in momentum space. When the honeycomb lattice sites are helically ordered along the propagation direction, gaps open at Dirac points, and one obtains a PFTI in an atomic vapor. An obliquely incident beam will be able to move along the zigzag edge of the lattice without scattering energy into the PFTI, due to the confinement of edge states. The appearance of Dirac cones and the formation of a photonic Floquet topological insulator can be shut down by the third-order nonlinear susceptibility and opened up by the fifth-order one.
