We demonstrate a four-port optical switch for the photonic network-on-chip architecture, which contains four silicon Mach-Zehnder optical switch elements tuned by the plasma dispersion effect. The optical signal-to-noise ratio of the device is over 10.0 dB in the wavelength range from 1525 nm to 1565 nm. Its 10%–90% rise time and fall time are 2 ns.
Photonic Network-on-Chips (NoCs) have recently been proposed due to their inherent low latency and high bandwidth. However, the high static power of the photonic components (e.g. laser source, resonators and waveguides) often results in energy-inefficient architectures. In this paper, we advocate the Energy-Star Photonic Network (ESPN) architecture that optimizes energy utilization via a two-pronged...
Photonic integrated technologies are a widely accepted platform to overcome electronic limitations for short reach interconnections. Indeed, recent experiments have demonstrated their viability for both chip-level and board-to-board interconnects. In this context, microring resonators have the potential to become key components thanks to their versatility, high switching speed, low power consumption...
In this paper, we propose a novel circuit-switched on-chip photonic interconnection network (CSPIN) architecture. Different from existing circuit-switched photonic networks, CSPIN eliminates the electronic control layer but employs optical signaling to control the circuit switching functions. To implement CSPIN, the CSPIN router is proposed which uses electro-optical tuned micro-ring resonators. The...
In this paper we propose to use comb switches to simplify Banyan-type on-chip wavelength-routed passive photonic networks constructed by micro-ring resonator (MRR)-based optical switches. Compared with general wavelength-routed optical networks, the number of MRRs used in the simplified network is significantly reduced.
The emerging field of silicon photonics targets monolithic integration of optical components in the CMOS process, potentially enabling high bandwidth, high density interconnects with dramatically reduced cost and power dissipation. A broadband photonic switch is a key component of reconfigurable networks which retain data in the optical domain, thus bypassing the latency, bandwidth and power overheads...
Wavelength-selective spatial routing is proposed for photonic networks and demonstrated on an electro-optic microring switch. This technique yields greater path diversity in photonic networks, enabling improved overall network performance.
The paper presents a novel energy efficient routing scheme for photonic network on chip (PNoC) based on the microresonator which takes the insertion loss and the path-setup latency into consideration in order to design a high performance per watt multi-processors. The path-setup latency is a major contributor to the whole system's latency that has something to do with queuing. And insertion loss which...
We present two paradigms to realize all-optical packet switches, and report experimental results showing the routing operation of the 160 Gb/s packets and beyond. Photonic integrated sub-systems required to implement the packet switch are reviewed.
Photonic networks on chip (NoCs) have emerged as the future generation of chip multiprocessors. Routing algorithm is an important aspect to determine the performance of photonic NoCs. In this paper, we have proposed a new model called the XY-turn model for designing partially adaptive or deterministic routing algorithms for honeycomb networks on chip without adding virtual channels. The model prohibits...
Wavelength-selective optical processing using collinear acoustooptic (AO) swtiches will be useful in photonic routing systems. We have studied on the applications to optical label recognition in label routers. We propose recognition of hierarchical routing labels encoded in binary-phase-shift-keying (BPSK) format with an AO processor consisting of optical delay waveguides and parallel double-stage...
Photonic networks-on-chip have emerged as a viable solution for interconnecting multicore computer architectures in a power-efficient manner. Current architectures focus on large messages, however, which are not compatible with the coherence traffic found on chip multiprocessor networks. In this paper, we introduce a reconfigurable optical interconnect in which the topology is adapted automatically...

We investigate hierarchical label recognition for optical codes encoded in time and spectral domains. A proposed integrated-optic acoustooptic processor can recognize partial labels. The device is useful for layer control of routing.
The agile all-photonic network (AAPN) is a network that uses time division multiplexing (TDM) to better utilize the bandwidth of WDM systems. AAPN uses agile all-photonic switches as advances in the photonic switching technology made the design of all-photonic devices with switching latency in the sub-microseconds feasible. It proposes a simplified overlaid star network architecture that is deployable...
In this work we investigate the effects of multiple access interference (MAI) and polarization mode dispersion (PMD) in optical code division multiplexing (OCDM) lightpaths. These paths are determined by the data encoding with non-coherent optical orthogonal codes (OOC), using a sequence inversion keying (SIK) optical correlator system. Our results show the impact of MAI effects and PMD constraint...
This paper describes a new path computation model in Multi-protocol Label Switching (MPLS) and Generalized MPLS (GMPLS) networks. It introduces a path computation element (PCE), which is functionally separate from label switching routers (LSRs). The Path Computation Element (PCE) is an entity that is capable of computing a network path or route based on a network graph, and applying computational...
We propose a new label recognition system for photonic packet routing using self-routing of labels. Whole binary-coded labels modulated in phase can be recognized with a circuit consisting of tree-structure passive asymmetric-waveguide X-junctions.
