“…The 4-level pulse amplitude modulation (PAM-4) data format is one of solutions to approach for decoding the VCSEL because the half of modulation bandwidth for the PAM-4 data format is used to achieve the same data rate as compared to the NRZ-OOK data format 33,34 37 . In addition, Finisar Corporation demonstrated 4 channel 45 Gbps VCSEL chip over 300-m OM4 fiber by using the PAM-4 data format 38 . The BER of VCSEL chip is achieved below the KP4 criterion of 2×10 -4 , which further obtains the total data rate to 180 Gbps 38 .…”

This paper is going to review the state-of-the-art of the high-speed 850/940-nm vertical cavity surface emitting laser (VCSEL), discussing the structural design, mode control and the related data transmission performance. InGaAs/AlGaAs multiple quantum well (MQW) was used to increase the differential gain and photon density in VCSEL. The multiple oxide layers and oxide-confined aperture were well designed in VCSEL to decrease the parasitic capacitance and generate single mode (SM) VCSEL. The maximal modulation bandwidth of 30 GHz was achieved with well-designed VCSEL structure. At the end of the paper, other applications of the near-infrared VCSELs are discussed.

“…In this approach, the capacity of a single MMF scales with the number of wavelengths. Using a combination of signaling, equalization and SWDM, 200 m OM4 links operating at 42.5 Gbps [13], and 48.8 Gbps [14] per wavelength have been reported. SWDM technology is currently under IEEE 802.3 standardization process [15].…”

Data centre connections can greatly benefit from parallel transmission channels on one multimode fibre (MMF). Shortwave wavelength division multiplexing (SWDM) achieves parallel transmission through spectral multiplexing. Furthermore, MMFs offer a spatial dimension that should be exploited to increase parallel transmission, albeit in a cost-effective way. In this paper, it is shown that SWDM and spatial multiplexing can be combined in intensity modulation and direct detection MMF transmission systems that use selective offset excitation and mode-selective spatial filtering. Keywords: space division multiplexing, wavelength division multiplexing, multimode fibre, data centre network INTRODUCTIONIntra-data-centre optical connections are extensively employing graded-index (GI) multimode fibres (MMFs). Such MMF connections do not normally exceed a 500-m reach and should support the Gbps needs of the massive data centre networks. To achieve transmission of 100 Gbps and beyond, the following approaches have been considered: parallel optics in terms of parallel MMFs and MPO connectors, using advanced modulation formats such as pulse amplitude modulation and discrete multitone, and introducing shortwave wavelength division multiplexing (SWDM) by extending the 850-nm window and employing wideband MMFs [1], [2]. These approaches lead to solutions based on intensity modulation and direct detection (IM/DD). However, it is also the case that the MMF modes can be exploited by applying space division multiplexing (SDM) techniques. This can have significant advantages such as increasing the bit-rate-distance product, or reducing the number of parallel MMFs required. Applying SDM with IM/DD on GI-MMFs is possible and can be realized with selective offset excitation and mode-selective spatial filtering (MSSF) [3], [4].In this paper, we explore the application of IM/DD SDM with offset excitation and MSSF on 50/125 μm GIMMFs in a SWDM scenario. This scenario would require wavelength-selective optical filters that do not impact the mode power distribution that forms each spatial channel. This requirement can be met by WDM filters based on free-space optics and thin film filters [5]. It remains, though, crucial to investigate the application of SDM in terms of offset excitation and MSSF over the wavelength range proposed for SWDM. It is shown here that this IM/DD SDM approach can apply similarly on each SWDM channel, although the mode volume of the GI-MMF varies significantly within the SWDM wavelength range. Furthermore, the case of two IM/DD SDM channels can be realized without any additional signal processing requirements, presenting a very simple and straightforward scenario.
