META’15, the 6th International Conference on Metamaterials, Photonic Crystals and Plasmonics

City College of New York, New York City, NY, USA August 4, 2015 – August 7, 2015 The International Conference on Metamaterials, Photonic Crystals and Plasmonics (META) features every year the latest developments in the area of Nanophotonic, Metamaterials and related topics. The conference program consists of plenary lectures, keynote talks, special sessions of invited talks, general sessions and high-profile […]

Tomography for plasmonics

Tomography is an imaging technique that allows the reconstruction of a three-dimensional object from a collection of two-dimensional projection images. Images of almost any type can be used as long as the relationship between the two-dimensional projections and the object properties are known and satisfy the projection theorem: the image contrast should vary linearly with […]

Modeling of On-Chip Optical Nonreciprocity with an Active ...

Jianming Wen et al., report the modeling of on-chip optical nonreciprocity with an active microcavity. On-chip nonreciprocal light transport holds a great impact on optical information processing and communications based upon integrated photonic devices. By harvesting gain-saturation nonlinearity, they recently demonstrated on-chip optical asymmetric transmission at telecommunication bands with superior nonreciprocal performances using only one […]

Scientists build a nanolaser using a single atomic sheet

University of Washington scientists have built a new nanometer-sized laser — using the thinnest semiconductor available today — that is energy efficient, easy to build and compatible with existing electronics. Lasers play essential roles in countless technologies, from medical therapies to metal cutters to electronic gadgets. But to meet modern needs in computation, communications, imaging […]

Plasmonic Nanoantennas: From Nanotweezers to Plasmonic Pho...

Kimani C. Toussaint Jr., Brian J. Roxworthy, Hao Chen, Abdul M. Bhuiya and Qing Ding Devices that convert optical radiation to spatially concentrated energy at the nanoscale are finding applications in data storage, spectroscopy, sensing and nanoscale optical manipulation. They can even serve as a plasmonic “film” for recording images or encoding sound. For those […]

Plasmonic nanostructures for enhanced LED efficiency

Plasmonic nanostructures for enhanced LED efficiency

“Shih-Hao Chuang and Dong-Sing Wuu” “A novel transparent electrode embedded with silver-based nanoparticles enhances the light extraction efficiency of LEDs, improving device performance by 88%.” Due to the important role that they play in solid-state illumination, LEDs represent a promising candidate for next-generation lighting technology. However, confinement—which occurs due to the large difference in refractive […]

Fabrication and characterization of a surface plasmon resonance based fiber optic sensor for the detection of melamine using molecular imprinting are reported by Shrivastav et al. from Physics Department of Indian Institute of Technology in Delhi (February 2015).

Putting a new spin on plasmonics

Researchers at Aalto University have discovered a novel way of combining plasmonic and magneto-optical effects. Magnetic nanoparticles arranged in arrays put a twist on light: depending on the distance between the nanoparticles, one frequency of light (visible to the human eye by its colour) resonates in one direction; in the other direction, light (induced by […]

Plasmon-Assisted Audio Recording

Researchers at the University of Illinois at Urbana-Champaign have successfully recorded optically encoded audio onto a plasmonic nanostructure that is non-magnetic. This is considered to be the first ever recording of such an audio. This type of recording could be used for archival storage and informational processing.

DNA does design: 3D plasmonic photonic crystals are the fi...

Jan 14, 2015 by Stuart Mason Dambrot (Phys.org)—As biotechnology and nanotechnology continue to merge, DNA-programmable methods have emerged as a way to provide unprecedented control over the assembly of nanoparticles into complex structures, including customizable periodic structures known as superlattices that allow fine tuning the interaction between light and highly organized collections of particles. Lattice […]
