Fabrication and Characterization of 3D Square Spiral Photonic Crystals

Jensen M.O., Summers M.A., Brett M.J., University of Alberta, CA

Three-dimensional photonic crystals can be fabricated using the glancing angle thin film deposition technique (GLAD). These nanostructured thin films consist of a periodic array of micrometer-sized silicon square spirals, as proposed by O. Toader and [...]

Simulation Studies of Plasmon Enhanced Evanescent Near-Field Optical Lithography

Sefa-Ntiri B., Docker P., Ward M.C., Prewett P.D., University of Birmingham, UK

Evanescent Near-Field Optical Lithography (ENFOL) is an inexpensive route to nanolithography, overcoming the diffraction limitations of conventional optical technology. This paper details modelling work developed by the authors, to produce a predictive model that can [...]

Add-Drop Filters utilizing Vertically Coupled Microcavities in Silicon

Koonath P., Indukuri T., Jalali B., University of California, Los Angeles, US

Micro-resonant optical cavities facilitate dense integration of optical devices on a chip. Through vertical integration of devices, precise control over the critical dimension of the structure can be achieved. Add-drop multiplexers based on vertically coupled [...]

Optical Surface Diffraction and Improved Lateral Resolution

Bacsa W.S., Caumont M., CNRS, UPS, BU, US

Optical coherence plays an important role in the local field in the vicinity of surfaces where the incident and scatter field overlap (1). While phase differences are small in the optical nearfield, the longitudinal component [...]

Quantum Dots/Conductive Polymer Nanocomposite

Chen C-M, Chen H-S, Huang H-C, Chen C-M, Chen H-S, ITRI, TW

The nanocomposite composed of CdSe quantum dots and conductive polymer (MDMO-PPV) was investigated. The spherical 3.8-nm functionalized CdSe quantum dots were synthesized by colloidal chemical method. The conductive polymer MDMO-PPV was synthesized from 1-methoxyl-4-(3,7dimethyl-octanoxyl)benzene and [...]

Superposition Behavior in Babinet’s Effect on the Nano Au Particles Patterns

Wu S-C, Chen C-F, Chen H-L, Chao W-C, Chen C-F, Chen H-L, National Nano Device Laboratories, TW

The individual Babinet effect [1] in two types of complementary patterns can be added on a composed pattern mixed both patterns under the FTIR (Fourier Transform Infer-Red) spectroscopy measuring. That is the Babinet spectrum on [...]

Stochastic Analysis of Particle-Pair Transport in Brownian Ratchet Device

Retkute R., Gleeson J.P., University College Cork, IE

The motion of particle pairs in a Brownian ratchet device is studied using Langevin simulations. A Lennard-Jones interaction between the particles is added to a standard spring-bead model. The effects of such interaction upon a [...]

Multiscale (Nano-to-Micro) Design of Integrated Nanobio Systems

Jenkins J., Hagan M., Chakraborty A., Sundaram S., CFD Research Corporation, US

Biological systems have the first level of organization at the nanoscale. Proteins, DNA, RNA, ion channels are nanoscale systems that leverage molecular interactions to perform specific tasks. Integrated nano-bio systems have emerged as strong candidates [...]

A Minnow, an E. Coli and Ubiquinone: The Story of Rectified Brownian Motion

Fox R.F., School of Physics, US

Rectified Brownian motion provides a mechanistic alternative to the power stroke model for the function of motor proteins and other enzyme complexes. ATP is the source of metabolic free energy for motor proteins such as [...]
