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.
Recent studies on 1.3 mum InGaAs/GaAs QD-SOAs show they are able to deliver >18 dB gain across a 20 to 70degC temperature range. Successful system demonstrations over temperature are reported at channel rates of 10 Gb/s.
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 2x2 quantum dot switch for uncooled switching applications. High gain of 11.6dB and ≫0.6dB power penalty over 11dB dynamic range is demonstrated at temperatures up to 70°C.
1.3 mum QD SOAs are shown to provide 19 dB optical gain at temperatures up to 70 degC, allowing < 0.1 dB system penalty at 10 Gb/s. The gain is constant to within plusmn 3.5 dB from 20degC-70degC for 10 nm spectral bandwidth.
A novel ultrafast self routing system is demonstrated using four-wave-mixing of 10 Gb/s packets spectrally-encoded in 25 GHz grid bins which are unequally spaced. Codes with a maximum separation of 1.6 nm enable routing to 10 different ports.
A 32x32 optical RoF switch is demonstrated. A 13 dB input dynamic range with acceptable EVM and, using open loop control, an input dynamic range of 10 dB with 1 dB variation in output RF power is achieved.
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.
A practical non-blocking 32times32 SOA based switch architecture is presented which minimises the number of required cascaded stages while also requiring relatively few SOAs. This switch is robust and suitable for 8times10 Gb/s wavelength striped operation.
Abstract: We summarize the commercial needs for development of high capacity interconnects, specifically for short reach (backplane, board to board) applications and review the research challenges to be addressed for optically switched interconnects. We present recent work on our near term solution, SWIFT, for centrally controlled, single switch fabric, short link applications not requiring wavelength...
The robustness of an integrated 2times2 quantum-dot switch is investigated for low penalty operation. Near penalty free operation of <0.2 dB is demonstrated for IPDR of over 8 dB, highlighting its potential for systems applications.
Performance of packet switching at 4x40Gb/s through a multi-stage SOA is evaluated. Fault identification and rerouting in the multi-stage switch is demonstrated.
A layered architecture is shown for construction and management of large-scale multi-stage SOA switch. The scheme is implemented in a 40Gb/s multi-stage SOA switch network. Output power of each packet is controlled to within 0.5dB.
