We propose a new iterative algorithm for obtaining optimal holograms targeted to the generation of arbitrary three dimensional structures of optical traps. The algorithm basic idea and performance are discussed in conjunction to other available algorithms. We show that all algorithms lead to a phase distribution maximizing a specific performance quantifier, expressed as a function of the trap i...

The low cost per megabyte of optical disk and magnetic tape storage make these technologies particularly attractive for use in large capacity storage servers, including multimedia servers. However, these devices have performance problems that range from high costs for many optical drives to low performance and lack of random access in tape drives. We evaluate the performance on multimedia appli...

Metal-organic frameworks (MOFs) have been intensively studied over the past decade because they represent a new category of hybrid inorganic-organic materials with extensive surface areas, ultrahigh porosity, along with the extraordinary tailorability of structure, shape and dimensions. In this highlight, we summarize the current state of MOF research and report on structure-property relationsh...

The information age has brought with it an everincreasing demand for storage systems that have high capacity, fast data-transfer rate, and short access time. Vast memory systems are required for supporting the many storage-intensive computer applications such as multimedia, video on demand, and network-based computing. Optical memories already play an important role in existing commercial syste...

Scientific community has well recognized that a Lorentzian medium exhibits anomalous dispersion behavior in its resonance absorption region. To satisfy the Krammers-Kronig relation, such an anomalous region has to be accompanied with significant loss, and thus, experimental observations of negative group velocity in this region generally require a gain-assisted approach. In this letter, we demo...
