Colloidal quasicrystal for photonics

Silicon Photonics for Exascale

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 ...

Design Tools for Photonics

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...

Deceptions in Quasicrystal Growth

We discuss a new general phenomenon pertaining to tiling models of quasicrystal growth. It is known that with Penrose tiles no (de-terministic) local matching rules exist which guarantee defect-free tiling for regions of arbitrary large size. We prove that this property holds quite generally: namely, that the emergence of defects in quasicrystal growth is unavoidable for all aperiodic tiling mo...

Three?Dimensional Nanostructures for Photonics

Recent progress in direct laser writing of three-dimensional (3D) polymer nanostructures for photonics is reviewed. This technology has reached a level of maturity at which it can be considered as the 3D analogue of planar electron-beam lithography. Combined with atomic-layer deposition and/or chemical-vapor deposition of dielectrics—the 3D analogues of planar evaporation technologies, the 3D p...
