Ultracompact and low-power optical switch based on silicon photonic crystals.
Switching light is one of the most fundamental functions of an optical circuit. As such, optical switches are a major research topic in photonics, and many types of switches have been realized. Most optical switches operate by imposing a phase shift between two sections of the device to direct light from one port to another, or to switch it on and off, the major constraint being that typical re...
متن کاملTONAK: A Distributed Low-latency and Scalable Optical Switch Architecture
This paper proposes TONAK, an AWGR-based optical switch with distributed control plane. Simulations results for a 128-port switch show high throughput and low average packet latency for offered loads of up to 75%, while achieving an energy efficiency of ≈ 50pJ/bit. Introduction The ever-growing demand for cloud-based services and high-performance computing is posing major challenges to the scal...
متن کاملArchitecture of Reconfigurable a Low Power Gigabit AT Switch
Multistage switch interconnects like banyan switches are preferred in high speed networks for their cascadable structure and suitability for V U 1 implementation. However most of these switch implementations are monolithic in nature and do not provide flexibility of dynamic re-routing of cells from active ports through idle ports. In this paper we take a critical look at a basic 8 x 8 benes swi...
متن کاملOptimized Digital Optical Switch Using Proton Exchanged Lithium Niobate Waveguides
The main emphasis in developing DOS has been on achieving low crosstalk (CT). CT in the order of -30 dB is acceptable in conventional DOS and below that value is hard to achieve. Relatively low drive voltage (or power requirements) is also necessary to optimized DOS. This paper depicts the design of Y-branched digital optical switches (DOS) with optimized on-chip area coverage, reduced driving ...
متن کاملA Single-Atom Optical Switch
Quantum scientists over the past two decades have dreamt of realizing powerful new information technologies that exploit the laws of quantum mechanics in their operation. While many approaches are being pursued, a prevailing choice consists of using single atoms and particles of light—single photons—as the fundamental building blocks of these technologies [1]. In this paradigm, one envisions th...
