Fractional Lambda (λ) Switching (FλSTM) adds the necessary efficiency to Wavelength Division Multiplexing (WDM) while preserving the simplicity of whole λ switching. Due to its provisioning capability, from a fraction of STS-1 to a full optical channel capacity, FλSTM will extend the reach of optical networking all the way to the network edges in the metro and enterprise. Finally, FλSTM uniquel...

Classical approaches to quality-of-service (QoS) provisioning in IP networks are difficult to apply in all-optical networks. This is mainly because there is no optical counterpart to the store-and-forward model that mandates the use of buffers for queuing packets during contention for bandwidth in electronic packet switches. Since plain IP assumes a best

We summarize our research on LION switches exploiting wavelength routing in arrayed waveguide grating routers (AWGRs). We discuss the loopback-buffer, alloptical-NACK and all-optical-TOKEN architectures, presenting their effectiveness in terms of network performance and experimental studies.

We demonstrate a scalable and reconfigurable optical directed-logic architecture consisting of a regular array of integrated optical switches based on microring resonators. The switches are controlled by electrical input logic signals through embedded p-i-n junctions. The circuit can be reconfigured to perform any combinational logic operation by thermally tuning the operation modes of the swit...

We demonstrate that nonlinear directional coupler with special bending of waveguide axes can be used for all-optical switching of polychromatic light with very broad spectrum covering all visible region. The bandwidth of suggested device is enhanced five times compared to conventional couplers. Our results suggest novel opportunities for creation of all-optical logical gates and switches for po...

Over the last few decades, there has been a growing interest in all-optical approaches to computing and information processing 1 . All-optical approaches do not suffer from the intrinsic slow response of electronic components and have the potential for signal routing, processing, multiplexing, and demultiplexing with speeds exceeding terahertz THz rates. As is the case for electronic logic gate...

Multi-terabit optical time division multiplexing (OTDM) networks require semiconductor all-optical switches and wavelength converters operating at room temperature. These devices should be characterized by AN ultrafast response capable of sustaining high repetition rates with low switching energy and high contrast ratio. These features lead to consider the use of resonant nonlinearities for the...
