Abstract: The fabrication of asymmetric monometallic nanocrystals with novel properties for plasmonics, nanophotonics and nanoelectronics. Asymmetric monometallic plasmonic nanocrystals are of both fundamental synthetic challenge and practical significance. In an example, a thiol-ligand mediated growth strategy that enables the synthesis of unprecedented Au Nanorod-Au Nanoparticle (AuNR-AuNP) dimers from pre-synthesized AuNR seeds. Using high-resolution electron microscopy and tomography, crystal structure and three-dimensional morphology of the dimer, as well as the growth pathway of the AuNP on the AuNR seed, was investigated for this example. The dimer exhibits an extraordinary broadband optical extinction spectrum spanning the UV, visible, and near infrared regions (300-1300 nm). This unexpected property makes the AuNR-AuNP dimer example useful for many nanophotonic applications.

Abstract: There is provided an ultra-light decoder for high speed digital communications based on block codes such as turbo product codes (TPCs). The new decoder can perform soft decision decoding without an algebraic hard decision decoder, which is the core of conventional soft decision decoders. The elimination of algebraic decoder significantly reduces the number of computations required per codeword, consequently, it reduces the decoding delay and processing power. However, reducing the decoding delay would immediately enable increasing the transmission speed, and minimize the need for large buffers at the receiver. Moreover, reducing the complexity and delay would enable using codes with high code rates to increase the system capacity, or use powerful codes with low code rates to reduce the transmission power. Such benefits can be achieved for about 1 dB loss in coding gain. There is also provided a receiver comprising the ultra-light decoder, as well as a decoding process.
