“…Fig. 1 shows the transmission distance versus the line rate of the directly modulated VCSELs, complied from previously reported works [3]- [26]. An 850-nm VCSEL having a 3-dB modulation bandwidth as high as 26 GHz has been recently demonstrated and the record 71-Gb/s transmission has been reported by using this device [23].…”

“…However, a great deal of effort has been devoted for more than a decade towards alleviating these problems. Recently a 1.5-ȝm VCSEL with a 17-GHz modulation bandwidth has been reported by exploiting the short-cavity buried tunnel junction structure [3]. Thus recent advancement in reliability and performance of the long-wavelength VCSELs opens up the possibility of using these attractive devices for optical access networks.…”

We explore the possibility of utilizing 1.55-ȝm directly modulated vertical-cavity surface-emitting lasers (VCSELs) for the use in optical access networks. For this purpose, we experimentally investigate the transmission performance of high-speed (10~25 Gb/s) on-off keying (OOK) and 4-ary pulse amplitude modulation (PAM4) signals generated by using a 1.55-ȝm directly modulated VCSEL over standard single-mode fibers. The electronic dispersion compensation technique is employed at the receiver to maximize the transmission distance. Power budgets of the VCSEL-based optical links are presented over various transmission distances.

“…This temporal walk-off would give rise to bulges in the waveform of the recombined signal especially at the marks because the blue-shifted f 1 components travel faster than the red-shifted f 0 components in the anomalous dispersion region. This effect is introduced in a couple of references as the 'self-steepening effect' [24], [25]. Fig.…”

We evaluate the possibility of realizing optical access networks using 1.5-μm vertical-cavity surface-emitting lasers (VCSELs) in the on-off keying (OOK) and four-level pulse amplitude modulation (4-PAM) formats. In order to maximize the power budget of the networks, we optimize the extinction ratio of the 10.7-and 21.4-Gb/s signals and exploit the electrical equalization at the receiver. The experimental comparison made at 10.7 Gb/s shows that the OOK format vastly outperforms the 4-PAM format in terms of tolerance to chromatic dispersion. For example, we achieve the 80-km transmission of the OOK signal over standard single-mode fiber (SSMF), but the maximum reach is halved when the 4-PAM signal is employed. Nevertheless, the 4-PAM format is still an effective way to double the data rate of the VCSEL links in optical access networks. We successfully transmit the 21.4-Gb/s 4-PAM signal generated by using the 1.5-μm VCSEL over 18-km long SSMF.
