Integreated 2x2 optical switch with gain

A 2 x 2 optical switch based on semiconductor laser amplifiers with passive waveguide routers and corner mirrors is demonstrated. All paths show fibre-to-fibre gain for all polarisations, with 6dB gain achieved in the best case

Demonstration of programmable optical pulse pattern generator for 100 Gbit/s networks

A programmable 100 Gbit/s optical pulse pattern generator based on planar silica delay lines and semiconductor laser amplifier switches is demonstrated experimentally. The technology has key applications in ultrafast all-optical networks
