      Sketch drawing of an operating organic light-emitting transistor (OLET). The hole and electron flows are represented as “plus” and “minus” signs, respectively, that meet in the middle of the OLET channel. Due to the electron-hole interaction light is formed which is represented by a bright yellow sheet escaping from the device towards the viewer. (Picture: M. Muccini, W. Koopman, S.

    1. Silicon photonics: from a microresonator perspective (pages 145–177)

      S. Feng, T. Lei, H. Chen, H. Cai, X. Luo and A.W. Poon

      Article first published online: 1 AUG 2011 | DOI: 10.1002/lpor.201100020

      Silicon photonics leverages the optical, electrical and material properties of silicon and the mature complementary metal-oxide semiconductor (CMOS) nanofabrication technique to develop on-chip photonic integration, which has been making significant impact on various frontiers including next-generation optical communications networks, on-chip optical interconnects and biosensing. Among many optical structures fabricated on silicon chips, microresonators play an important role in various devices including lasers, filters, modulators, switches, routers, delays, detectors and sensors.

    2. Deterministic aperiodic nanostructures for photonics and plasmonics applications (pages 178–218)

      L. Dal Negro and S.V. Boriskina

      Article first published online: 6 JUL 2011 | DOI: 10.1002/lpor.201000046

      Thumbnail image of graphical abstract

      This review focuses on the optical properties and device applications of deterministic aperiodic media generated by mathematical rules with spectral features that interpolate in a tunable fashion between periodic crystals and disordered random media. These structures are called Deterministic Aperiodic Nano Structures (DANS) and can be implemented in different materials (linear and nonlinear) and physical systems as diverse as dielectric multilayers, optical gratings, photonic waveguides and nanoparticle arrays.

      3D THz metamaterials from micro/nanomanufacturing (pages 219–244)

      H.O. Moser and C. Rockstuhl

      Article first published online: 19 SEP 2011 | DOI: 10.1002/lpor.201000019

      Thumbnail image of graphical abstract

      Metamaterials are engineered composite materials offering unprecedented control of wave propagation. Despite their complexity, effective properties can frequently be extracted by conceptualizing them as homogeneous and isotropic media with dispersive electric permittivity and magnetic permeability. As the engineered sub-structures must be smaller than their design wavelength, micro/nanomanufacturing is exploited from primary pattern generation over lithography to templating and molecular beam epitaxy. 3D metamaterials have been made by stacking of layers, multilayer structuring, and 3D primary pattern generation.

      Frontispiece: Terahertz sensing and imaging based on nanostructured semiconductors and carbon materials (Laser Photonics Rev. 2/2012, page 246) (page 245)

      Article first published online: 12 MAR 2012 | DOI: 10.1002/lpor.201290000

      The advantageous properties of terahertz (THz) waves, such as permeability through objects that are opaque for visible light and the energy spectrum in the microelectron-volt range that are important in materials research, allow their potential use in various applications of sensing and imaging. However, since the THz region is located between the electronic and photonic bands, even the basic components such as detectors and sources have not been fully developed unlike in other frequency regions. THz technology has also the problem of low imaging resolution, which results from a considerably longer wavelength than that of the visible light. However, the utilization of nanostructured electronic devices has recently opened up new horizons for THz sensing and imaging. In his paper, Y. Kawano DOI 10.1002/lpor201100006 (pp. 246– 257) provides an overview of the THz detector and imaging techniques and tracks their recent progress. Specifically, two cutting-edge techniques, namely, frequency-selective THz-photon detection and integrated near-field THz imaging, are discussed in detail. Finally, the studies of superconductors and semiconductors with high-resolution THz imaging are described.

    2. The photonic perspective of organic light-emitting transistors (pages 258–275)

      M. Muccini, W. Koopman and S. Toffanin

      Article first published online: 13 SEP 2011 | DOI: 10.1002/lpor.201100008

      Thumbnail image of graphical abstract

      Organic light-emitting field-effect transistors (OLETs) are emerging as an innovative class of multifunctional devices that integrates the electronic properties of a transistor, the light-generation capability and the full potential of organic photonics. Recent significant advances, including the demonstration of OLET external quantum efficiency outperforming that of OLEDs based on the same emitting layer, brought the field at a stage where a full technology platform can be developed.
