This paper proposes a dynamic bandwidth and bandwidth allocation (DWBA) algorithm for time and wavelength division multiplexing passive optical networks (TWDM PONs). The proposed algorithm saves power by decreasing the number of active wavelengths of a TWDM PON system.

In this paper, we propose a time-token multi-Gb/s Wavelength Division Multiplexing Fibre Distributed Data Interface (WDM/FDDI) architecture and examine its throughput efficiency and delay under heavy load for different network configuration using discrete event simulator.

A wavelength-division optical vetwork (WON) is a multihop, multichannel lightwave network based on wavelength-division multiplexing. Its wavelength-selectable, multitransceiver stations can be tuned to form many different virtual topologies. We study in this paper routing and admission control in the WON. We review the performance of routing algorithms for store-and-forward, deflection, and det...

This paper demonstrated a multi-channel Wavelength-Division-Multiplexing (WDM) system using photonic crystal structures. The system consists of a waveguide that realized by a defect row of photonic crystal and high Q-value micro-cavities. Two-Dimension (2-D) Finite-Difference-TimeDomain (FDTD) method is performed for simulation in this paper. The results showed good ability to filter an inciden...

All-optical code conversion of 10 Gb/s BPSK codes without wavelength-shift by use of cross-phase modulation in an optical fiber for optical code division multiplexing networks is proposed and experimentally demonstrated.

This paper describes a receiver for Wavelength Division Multiplexed (WDM) optical networks that employs Subcarrier Multiplexing (SCM) techniques to implement the control channels. The control channels operate in the 1 GHz to 2 GHz band.

The virtually-imaged phased array (VIPA) is a side-entrance etalon with potential application as a high-resolution spectral disperser for wavelength division multiplexing. Here we present an approximate analytical spectral dispersion law for the VIPA, which we confirm experimentally.

Vastly growing data traffic demands across system interconnects have driven the need for increased bandwidth densities. Using a single silicon photonic link waveguide, mode-division and wavelength-division -multiplexing are performed simultaneously to garner an aggregate bandwidth of 60 Gb/s for error-free (BER

Wavelength Division Multiplexing (WDM) has been shown to be one of the most promising ways to exploit the enormous bandwidth of a single mode optical ber. Networks employing WDM are commonly based on optical passive star couplers. The major cost and limitations of such networks lie in the interface (both transmitters and receivers) providing optical-electronic conversion between stations and co...

We propose a dynamic wavelength and bandwidth allocation algorithm with QoS (quality-ofservice) for a TWDM PON (time and wavelength division multiplexing passive optical network) system of NG-PON2 (next generation PON stage 2). Unlike other existing methods, the proposed method supports multiple service classes and is compliant to the NG-PON2 recommendation. To increase the wavelength allocatio...
