This paper presents a novel and effective stra-tegy for routing custom integrated circuits as well as solutions to subproblems associated with this strategy. Given an initial placement of rectangular ...
Many photonic structures, including waveguides, lenses, and photonic bandgap materials, benefi t greatly from the large index contrast provided by such media.
We report on the latest advances in implementation of integrated photonic components required for optical routing and switching: tunable wavelength converters, mode-locked lasers,active optical switch...
Direct communication between ONUs is experimentally demonstrated with a tunable MG-Y laser in a ring+tree PON for 640 users, without passing electrically powered equipment.
We show how inaccuracies of Quality of Transmission (QoT) estimations, caused by imperfect models and lack of monitors in transparent optical networks, can be mitigated using a novel routing and wavel...
A time-WDM architecture with on-the-fly wavelength routing and traffic self-aggregation is proposed.Metro-accesss ligthpaths are established using ONUs with reflective modulators. Simulations results ...
We introduce the Power-Aware RWA problem, whose goal is to accommodate lightpaths in wavelength routing networks minimizing the power consumption. Formulation, algorithms, and results are presented, s...
We propose and demonstrate a novel technique for interconnecting AWG-based wavelength routing networks. Experiments successfully demonstrated that this enables us to establish full-mesh wavelength pat...
We propose an optimization framework for routing virtually-concatenated 100 Gb/s Ethernet signals over optical transport networks with optimal buffer dimensioning and minimum capacity requirements in ...
An efficient ROADM-ring connecting node architecture is proposed that utilizes waveband routing and achieves small footprint and cost-effectiveness. The key component devices are implemented using PLC...
This paper demonstrates the benefits of GMPLS-based integrated routing and grooming in a 16-Node ASON/GMPLS network test-bed. Experimental results highlight significant blocking probability and E/O po...
A new cost-effective FTTH network with high bandwidth efficiency and extreme flexibility is demonstrated. FlexPON uses a stack of coloured PONs combined with remote wavelength routing allowing capacit...
We propose and evaluate a novel survivable Impairment Constraint Based Routing (ICBR) algorithm with service differentiation at the Bit Error Rate level. Simulations show significant improvement in co...
This paper evaluates the balance between the cost of multifibres and the cost of wavelength converters in multilayer networks. A novel ILP formulation of the static planning problem is applied.
The number of OEO regenerators required for a fixed blocking probability in a translucent network can be reduced drastically, if physical layer impairments are considered during regenerator placement ...
