Smyth, Frank and Connolly, Eoin M. and Mishra, A.K. and Ellis, A.D. and Cotter, D. and Kaszubowska-Anandarajah, Aleksandra and Barry, Liam P. (2006) Effects of crosstalk in WDM optical label switching networks due to wavelength switching of a tunable laser. IEEE Photonics Technology Letters, 18 (20). pp. 2177-2179. ISSN 1041-1135

rosstalk caused by switching events in fast tunable lasers in an optical label switching (OLS) system is investigated for the first time. A wavelength-division-multiplexed OLS system based on subcarrier multiplexed labels is presented which employs a 40-Gb/s duobinary payload and a 155-Mb/s label on a 40-GHz subcarrier. Degradation in system performance as the transmitters switch between different channels is then characterized in terms of the frequency drift of the tunable laser.
