A class of packet switching systems with inverse multiplexing of switched connections and/or flows (the SCIMUX architecture) has been recently proposed. Such systems open the possibility to use the readily available switch fabrics and port cards in order to build fullyfunctional packet switches, operating at rates much higher than those of their own components taken in isolation. While a compre...

Abstract Here, we introduce a tailorable coupled resonator surface acoustic waveguide (CRSAW), based on linear defect of elliptical cylinders inside phononic crystal ZnO pillars Si substrate. The designed resonators allow the emergence minimally dispersive, monomode shear-guiding band local resonance bandgap, owing to their partially broken structural symmetry in comparison with previously repo...

Self-assembly is a process in which basic units aggregate under attractive forces to form larger compound structures. Recent theoretical work has shown that pseudo-crystalline self-assembly can be algorithmic, in the sense that complex logic can be programmed into the growth process [26]. This theoretical work builds on the theory of twodimensional tilings [8], using rigid square tiles called W...

InP HBT technology appears to offer the high speed, low power and basic producibility necessary to support a high-speed digital IC technology. Maximum clock speed of 53 GHz has been demonstrated at 40 mW per flip-flop (FF) as compared to well over 200 mW/FF for SiGe at slower speeds. At a power dissipation of less than 9 mW/FF, toggle rate is still a respectable 35 GHz. Producibility and high s...

Traditional signal processing algorithms rely heavily on models that are inherently linear. Such models are attractive both for their mathematical tractability and their applicability to the rich class of signals that can be represented with Fourier methods. Nonlinear systems that support soliton solutions share many of the properties that make linear systems attractive from an engineering stan...

Based on the concept of low-frequency spoof surface plasmon polaritons (spoof SPPs), a kind of leaky mode is proposed in a waveguide made of a subwavelength metal-block array with open slots. Numerical results reveal that a new transmission mode is found in the periodic subwavelength metal open blocks. This modal field is located inside the interior of a hollow block compared with that in a sol...

Beam forming is a signal processing technique used in antenna arrays for directional signal transmission or reception. Phased array radar is very important in modern radar development, and multiple digital beams forming technology is the most significant technology in phased array radar. Digital multiple beam forming on each antenna element about large phased array radar is impossible in proces...

The Internet is an extremely convenient network and has become one of the key infrastructures for daily life. However, it suffers from three serious problems; its structure does not suit traffic centralization, its power consumption is rapidly increasing, and its round-trip time (RTT) and delay jitter are large. This paper proposes an extremely energy efficient layer-3 network architecture for ...

This paper reviews photonic crystal (PC) based demultiplexers, and briefly reports our latest experimental achievement in ultra-compact, power-efficient silicon photonic crystal waveguide (PCW) modulators. We review the modeling techniques for photonic crystal superprism devices, which utilize anomalous refraction on a photonic crystal surface for wavelength demultiplexing. The finite differenc...

In this paper, we experimentally demonstrate an optical frequency comb (OFC) based transmitter, employing directly modulated active demultiplexers, for data center interconnects. The results validate that the proposed transmitter has potential to achieve aggregate rates of 100 Gb/s (8 × 12.5 Gb/s) and 200 25 systems 4- 16- quadrature amplitude (QAM) discrete multi-tone (DMT) modulation. An OFC ...
