Special Issue Information

Dear Colleagues,

The 11th International Conference on Nanophotonics (ICNP 2018), will be held on 2–6 July, 2018, at the Wrocław University of Science and Technology, Wrocław, Poland. ICNP is a unique event where the latest advances in optics and photonics, both in nano- and micro-scales, are reported and discussed. It was conceived with the primary aim of bringing researchers from around the globe together to present novel ideas in nanophotonic science and technology with social and economic impacts, in areas of global concern. The topics of discussion include applications of nanophotonics from information processing to communications; from biomedical to life sciences; from energy harvesting and storage to environment and conservation. The conference’s broad themes and highly exciting 21st century challenges, ensure that researchers at all levels in this growing field to have an excellent opportunity to report their work and exchange information with fellow co-workers.

In the past two decades, nanophotonics has emerged as a multidisciplinary frontier of science and engineering, which is capturing the imagination of many researchers worldwide because of its vast potential to unleash breakthroughs in many areas of technology. It has already expanded our physical intuition beyond the usual boundaries of science, including engineering the photon density of state, negative index materials, cloaking, and generalizing Snell’s law.

This Special Issue on nanophotonics is expected to select excellent papers on the topic of nanophotonics; contributions from researchers who did not attend the ICNP are welcome and will be given full consideration. It aims to explore novel ideas in nanophotonic science and technology that enable technological breakthroughs in high impact areas including, but not limited to:

• Nanoplasmonics
• Metamaterials and metasurfaces
• Photonic Crystals
• Random and Nanolasers
• Nanofibers and integration
• Self Assembly and Nanochemistry
• Nanobiophotonics: Imaging, Sensing, Nanomedicine
• Nano-optoelectronics
• Nanofabrication and Nanocharacterization
• Green Nanophotonics, e.g., Photovoltaics
• Modeling and Simulation at the nanoscale
• Quantum Optics and Computing at the Nanoscale
• Silicon Photonics
• Nonlinear Optics at the Nanoscale

We also cordially invite researchers from the conference who would like to publish their original research articles in this Special Issue.

Open AccessArticle Laser Sintering of TiO2 Films for Flexible Dye-Sensitized Solar Cells

In this study, laser sintering of TiO2 nanoparticle films on plastic substrates was conducted in order to improve the incident photon-to-electron conversion efficiency (IPCE) of flexible dye-sensitized solar cells (DSCs).

In this study, laser sintering of TiO2 nanoparticle films on plastic substrates was conducted in order to improve the incident photon-to-electron conversion efficiency (IPCE) of flexible dye-sensitized solar cells (DSCs). Lasers with different wavelengths (355 nm and 1064 nm) were used to process the TiO2 electrodes. With an optimized processing parameter combination, the 1064 nm laser can sinter 13 μm thick TiO2 films uniformly, but the uniform sintering cannot be achieved by the 355nm ultraviolet (UV) laser, since the films possess a high absorption ratio at 355 nm. The experimental results demonstrate that the near-infrared laser sintering can enhance the electrical connection between TiO2 nanoparticles without destroying the flexible plastic substrate, reduce the transmission impedance of electrons and increase the absorption rate of incident light. Furthermore, the charge collection efficiency, fill factor, and short-circuit current have all been improved to some extent, and the solar conversion efficiency increased from 4.6% to 5.7%, with an efficiency enhancement reaching 23.9%.

Nonlinear optical dyes doped in optical polymer matrices are widely used for electro-optical devices. Linear optical properties change with dye concentration, which leads to a change in modal properties, especially in nano-structured integrated waveguides such as silicon slot-waveguides. Here, we investigate the influence of a nonlinear optical dye on the performance of a silicon-organic hybrid slot-waveguide. A simulation study of the modal and optical confinement properties is carried out and dependence of the structural parameters of the slot-waveguide and the organic cladding material is taken into account. As cladding material, a guest-host polymer system is employed comprising the nonlinear optical dye Disperse Red 1 (DR1) doped in a poly[methyl methacrylate] (PMMA) matrix. The refractive indices of doped and undoped PMMA were deduced from ellipsometric data. We present a guideline for an optimized slot-waveguide design for the fabrication in silicon-on-insulator technology giving rise to scalable, high-performance integrated electro-optical modulators.
