PM-QPSK 100G coherent technology based packet optical solution is creating new multilayer convergence network architecture. The black link standardization is expanding from 10G to 100G physical interfaces and leads to line side interoperability between different vendors. In addition, efforts are under way to define a network management interface. A packet optical solution is reviewed and the operation...
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.
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.
A monolithic add-drop switch incorporating an InGaAs quantum-dot active layer is presented, and 10Gb/s dual wavelength operation is demonstrated. No impairment in device performance is observed as a result
