Paper Abstract

A comprehensive numerical model has been applied to simulate single and multimode vertical-cavity surface-emitting lasers (VCSELs) with pseudorandom modulation of the current at a rate of 10 Gb/s. Eye diagrams, probability density functions of the power at the decision time, averaged turn-on delay and timing jitter are analysed for different values of the on and off-state currents. Extensive simulations have been performed to obtain the Bit Error Rate (BER). We find that the BER performance of single-mode VCSELs is better than the one obtained with multimode VCSELs when the off-state current is smaller than the threshold current and when the off-state current is larger than the threshold value, providing that the on-state current is large enough. However BER in single-mode VCSELs is greater than in multimode VCSELs when the off-state current is equal to the threshold current and when the off-state current is larger than the threshold value, if the on-state current is small enough
