Paper Abstract

An autonomic network control scheme is presentd for wavelength-division multiplexing based photonic networks. An aboslute wavelength control scheme using a disk-shaped wavelength tunable optical bandpass filter is presented. The wavelength reproducibility of 0.02 nm for the entire tuning range at various temperatures is promising for the automonic wavelength management. To verify the control scheme, an optical add/drop multiplexing subsystem is constructed using optical switches utilizing oil latchign interferential tension effect and wavelength-tunable devices. Its detailed operating performances are experimentally evaluated. The switching speed of less than 20 ms and extinction ratios of less than 45 dB of the switching element are allowable in practical systems. Error-free transmission performance at 10 Gbps with negligible coherent cross talk at an intersection of the switch is obtained. The optical carriers generated by a wavelength-tunable ring laser usign a disk filter, are allowable for data transmissions. These results show that the autonomic entwork contorl scheme is feasible.
