A proof-of-concept prototype of optical sub-wavelength switching fabric is demonstrated. The prototype supports petabit switching capacity with agile service granularity and low power consumption.
We propose a coherent burst-mode receiver structure for receiving multi-wavelength short PDM-QPSK optical bursts. Data-aided algorithms are employed for fast-tunable LO transients compensation and channel estimation to facilitate rapid data recovery.
We propose an optical burst ring network featuring both sub-wavelength- and wavelength-granularity grooming. Thanks to optical-layer transparency at network nodes, a large number of transponders for optical-electrical-optical conversion are saved. The use of fixed-tuned transmitters and regular optical amplifiers leads the burst network compatible with present WDM networks and feasible for deployment,...
We propose and demonstrate optical time interleaving of an optical RZ-ASK signal with an optical RZ-DPSK signal to form a hybrid OTDM signal, which does not require optical time demultiplexing at the receiver for detection.
