Accepted Abstract Temperature-controlled Raman microscopy to study the phase behaviour of synthetic PEGylated lipids and nanovesicles The study of phase transitions in lipids is important for understanding various phenomena such as trans-membrane diffusion, vesicle formation and fusion as well as drug-and protein-membrane interactions. Several techniques have previously been employed to investi...

With the extraordinary growth in parallelism at all system scales driven by multicore architectures, computing performance is increasingly determined by how efficiently high bandwidth data is communicated among the numerous compute resources. High-performance systems are especially challenged by the growing energy costs dominated by data movement. As future computing systems aim to realize the ...

Ti:Sapphire (Ti:Sa) was initially proposed and demonstrated as a near-infrared gain medium in 1982, and was commercialized by Spectra-Physics in 1988 with the launch of a continuous-wave laser. Th is was followed in 1990 by a picosecond mode-locked oscillator, and in 1991 with a femtosecond version. Soon aft er this, the whole ultrafast research community, which until then had been using visibl...

Cutting or welding heavy metal requires higher laser output power than virtually any other type of materials processing application. In the oil industry, an important heavy metal cutting application is creating the slotted liners used to separate oil from well sediments such as sand and gravel. Traditionally, this was done with diffusion-cooled CO2 slab lasers, but now, kilowatt-class fiber las...

Commercial success in the photonics marketplace dictates a full understanding of the product development lifecycle. Underpinning this success is the maximization of performance and minimization of product development time. These can be afforded at an early stage by employing computer design and simulation methodologies, enabling cost-effective and rapid evaluation of component performance prior...

Europium doped transparent lead fluorophosphate glass ceramics successfully were prepared with heat treatment of precourse glasses at temperature above glass transition (Tg). X-ray diffraction (XRD) experiment evidenced the formation of PbF2 nanocrystals in glassy matrix. The emission spectra investigation indicate that considerable amount of Eu3+ ions were trapped in crystalline phase, and the...

An AlGe eutectic wafer level bonding process is presented and characterized for heterogeneous integration of silicon photonics, CMOS integrated electronic circuits and active III-V components. Heterogeneous Integration of Photonics and CMOS The technology of silicon photonics integrated circuits (SiPIC) currently finds itself transitioning from research to industrial scale production [1]. The p...

The following text is excerpted from the upcoming second edition of the book Photonic Crystals: Molding the Flow of Light (Princeton University Press), scheduled for publication in 2007. In particular, although the book is mainly focused on the general principles of photonic crystals and related devices, it includes a survey of computational methods in the form of an appendix, which we reproduc...
