“…A promising format is the n-level pulse amplitude modulation (PAM-n) due to its higher spectral efficiency and easier implementation than that of other proposed modulation formats. An equalized PAM-4 is reported at 70 Gbps in a 2 m MMF link [2] and at 48.7 Gbps in 200 m OM4 MMF link [3]. Moreover, un-equalized PAM-8 is presented at 37.5 Gbps over 100 m OM4 [4].…”

“…For this reason, linear behavior around the operating point must be guaranteed. The most significant transmission studies on PAM and 850 nm VCSELs are gathered in Figure 17, which shows the effective data rate vs. MMF transmission length reported in Refs [48][49][50][51][52][53][54][55][56][57][58][59].…”

Application of nanophotonics to the next generation of surface-emitting lasers

Novel trends and concepts in the design and fabrication of vertical cavity surface-emitting lasers (VCSELs) and their integration in optical networks and implementation in integrated photonics applications are discussed. To serve these goals and match the growing bandwidth demands, significant changes are to be implemented in the device design. New lateral leakage-mediated singlemode VCSELs, including both devices confined by oxide layers and those confined by alloy-intermixed regions, are likely to be good candidates for light sources for the data networks of the future. An overview of the records in VCSEL transmission distances and transmission speeds is discussed in this context.

“…For example, a 43 Gbps link operating error-free without FEC up to 100 m on OM4 fiber (57 Gbps at 1 m) has recently been demonstrated using NRZ signaling [2]. To further push the VCSEL capacity, other signaling protocols such as PAM4, signal processing such as Forward Error Correction (FEC), and other digital signal processing techniques are being investigated [3,4,5]. For example, a two-tap feed-forward equalizer (FFE) on the transmitter (TX) side enabled error-free NRZ transmission without FEC up to 71 Gbps over 7 m OM4 [6], and 60 Gbps over 107 m OM4 [7].…”
