The rising popularity of cloud computing and big data applications has led to massive volumes of rack-to-rack traffic featuring diverse communication patterns denoted as *-cast that combines unicast, multicast, incast and all-to-all cast. Effective support of these traffic patterns in data center networks is still an open problem. We propose a hybrid (optical and electrical) approach that leverages...
The design of a unique bidirectional 2×2 SOA-based optical switch is detailed and experimentally validated. Error-free operation and routing correctness is verified for 4×10Gb/s pseudorandom messages.
We propose a novel fully-integrated scalable photonic switch architecture for data center networks, sustaining nonblocking 256×256 port size with nanosecond-scale switching times, interconnecting 2,560 server racks with 51.2-Tb/s bisection bandwidth.
A compact and efficient control plane has been implemented to demonstrate multipath routing for a twenty-electrode photonic integrated circuit with round-robin scheduling. A single slot clock with 3.2 μs packet period dynamically cycles connections between all input and output ports.
A 4 times 4 integrated SOA switch performs routeing and wavelength-conversion without additional active components. 0.6 dB penalty is achieved for 5 Gb/s wavelength-conversion, with 7 Gb/s error-free operation in this un-optimised device.
A novel Quantum Dot monolithically integrated 1×8 switch is shown to provide robust routing of data at 10Gb/s modulation rates. Two cascaded switches providing, 1×64 functionality, operate with a power penalty of only 0.9dB.
10Gb/s error-free operation of the first monolithic 16×16 quantum well semiconductor optical amplifier switch is demonstrated. The switch has a 2dB facet-to-facet gain and a minimum power penalty of 2.5dB.
The first high data-capacity routing in a 3-stage switch using integrated 4times4 QW-SOA circuits is reported. The feasibility of a proof-of-principle 16times16 routing switch is demonstrated for 8lambdatimes10Gb/s operation, with an IPDR of 6dB.
A priority encoding scheme is introduced for an optical switching fabric testbed, resolving contention by dropping low priority messages. Optical packets with 6times10 Gb/s payloads are routed error-free.
A fibre-to-fibre lossless integrated 4times4 SOA switch achieves an IPDR ~6 dB at <2 dB penalty for 8lambdatimes10 Gb/s. 10 Gb/s cascaded operation of two 4times4 switches is demonstrated.
This paper highlights the potential of an integrated 2times2 quantum dot switch for uncooled switching applications. High gain of 11.6 dB and <0.6 dB power penalty over lldB dynamic range is demonstrated at temperatures up to 70degC.
The performance of an integrated quantum dot switch, exhibiting on-chip gain in excess of 15 dB and saturation powers in excess of 12 dBm for both through and cross configurations, is presented. The device allows for the processing of picosecond pulses generated by a QD mode-locked
