Low-loss and low-crosstalk 8 × 8 arrayed waveguide grating (AWG) routers based on silicon nanowire waveguides are reported. A comparative study of the measurement results of the 3.2 nm-channel-spacing AWGs with three different designs is performed to evaluate the effect of each optimal technique, showing that a comprehensive optimization technique is more effective to improve the device perform...

At the heart of IP backbone networks are the core IP routers with throughput of hundreds of Gb/s. These routers with interfaces operating at the per-wavelength bit rates are directly connected via point-to-point WDM opticaltransport systems. For acceptable service reliability even for best effort services typically two interconnected routers are used for redundancy in each backbone node. It has...

This paper describes multi-layer traffic engineering and signaling technologies in the photonic-GMPLS-router (Hikari-Router) network. Multi-layer t 6 c engineering, which yields the dynamic cooperation of IP and photonic layers, is described with the goal of providing IP services costeffectively. The establishment of photonic cut-through paths is triggered when the Layer 3 traf€ic loads become ...

A Quantum dot implanted within a double-sided optical microcavity is considered and investigated as critical component for all optical-based quantum internets. Due to the duality photonic transistor gate, QD cavity system repsents sturdy base future network. With help of analytical investigation review presented in this paper, unit can be developed implementing deterministic gates transistors. ...

This paper presents a complete design for an optical Internet router based on decomposing the steps required for IP packet forwarding. Implementations of hopcount decrement and header matching are integrated with a simulation-based approach to variable-length packet merging that avoids recirculation, resulting in an all-optical data plane. A method for IPv4 checksum computation is introduced, a...

Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as refer...

The paper addresses the topic of long-haul optical networking for the provision of large-bandwidth IP services. A class of optical packet switching architectures is considered which adopts an arrayed wavelength grating device as packet router. The architecture performs slotted packet switching operations and fully exploits the wavelength routing capabilities by allowing multi-wavelength switchi...

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 ...
