1.28 Tbit/s throughput 8×8 optical switch based on arrays of gain-clamped semiconductor optical amplifier gates

Integrated gate matrix switch for optical packet buffering

“…The SOA gate matrix switch is the most promising switch choice for recirculating buffers primarily because other switch types can not reach the crosstalk requirement. In the past, gate matrix switch designs have been studied for fast switching [9], developed for high gain [10], and measurements have been performed up to 1 [11] and 10 Gb/s [12]. To the best of the authors' knowledge, this letter is the first to evaluate gate matrix performance up to 40 Gb/s.…”

Photonic Integrated Semiconductor Optical Amplifier Switch Circuits

“…The packaged array of 32 gain clamped SOA gates (Sahri et al, 2001) has enabled the most extensive system level assessments in telecommunications test-beds (Dittmann et al, 2003). Implementation of arrays of eight gates have also led to the early demonstrations of 8×8 optical switching matrices based on SOA gate arrays with 1.28Tbit/s (8×16×10Gb/s) aggregate throughput (Dorgeuille et al, 2000). These approaches rely on fiber splitter networks.…”

Semiconductor lasers and integrated devices

“…New generations of 8-gate Gain Clamped SOAs [Dorgeuille 2000] have been recently developed, demonstrating WDM switching experiments (16 wavelengths × 10 Gb/s). …”
