“…After 44 years of development, remarkable progress has been made on the development of VCSELs, and many researchers have demonstrated ultra-fast VCSELs with modulation bandwidths of up to 30 GHz [22,[61][62][63][64][65]116]. Some of the selected works on 850 nm VCSELs are shown in Figure 16 and Table Y e a r Note: This table summarizes the maximum data rates and 3-dB bandwidths at RT (unless stated otherwise) reported in these manuscripts.…”

“…Valuable progress has been made in the development of devices and advanced modulation formats to enable high modulation responses and energy-efficient and rapid data transmission using VCSELs in the last few decades. Significant achievements have been made in the improvement of 850 nm VCSELs' modulation bandwidths, and the fastest reported 3 dB modulation bandwidth to date is ∼30 GHz [22,[61][62][63][64][65]116]. On the other hand, more work has to be done to standardize and commercialize these high-speed 850 nm VCSELs in commercial transceivers to enable the future 800 GbE and 1.6 TbE Ethernets.…”

“…In the following year, Huang et al demonstrated 54 Gb/s error-free BtB transmission, as shown in Figure 5 [60]. In 2021, Chorchos et al from VI Systems GmbH (VIS) and the Warsaw University of Technology (WUT) reported a record 80 Gb/s using feed-forward equalization (FFE) technology with a 30 GHz VCSEL and BiCMOS driver packaged into a 33 GHz transceiver[61]. The latest reported 3 dB modulation bandwidth of an 850 nm VCSEL at RT was ∼30 GHz[22,[61][62][63][64][65], as they were close to the bandwidth limits of the VCSEL's intrinsic responses.…”

Vertical-cavity surface-emitting lasers (VCSELs) have made remarkable progress, are being used across a wide range of consumer electronic applications, and have particularly received much attention from the telecom and datacom industries. However, several constraints are thus currently being tackled to improve the device characteristics and modulation formats to meet the various demanding requirements of the future 800 GbE and 1.6 TbE Ethernet standards. This manuscript discusses the device characteristics and the key considerations in the device designs and optimizations. Finally, we elucidate the latest developments and vital features of modern 850 nm VCSELs for high-speed interconnects.

“…In 2018, Ledentsov et al operated the VCSEL temperature at 150 o C to allow the 25-Gbit/s NRZ-OOK transmission [28]. In 2020, Chorchos and co-workers demonstrated the NRZ-OOK transmission carried by the 850-nm VCSEL at 80 Gbit/s over 2-m MMF and 72 Gbit/s over 50-m MMF [29]. From the previous reports about the NRZ-OOK data transmission in Fig.…”

The developing progress on the structural design and data algorithms to enable the vertical-cavity surface-emitting lasers (VCSELs) for transmitting multiple complex data formats beyond 100-Gbit/s has been reviewed in this paper. Up to now, academic and industrial institutions still keep their research pace on studying how to improve the allowable data rate of various data formats carried by the VCSEL device. Persistent efforts are endeavored not only to achieve the IEEE802.3 standards for data center applications but also to initiate the new era of wired and wireless network coverage. To date, the highest allowable data rates of the single-VCSEL-based optical link for transmitting the NRZ-OOK format at 80 Gbit/s in the BtB case, the PAM-4 format at 168 Gbit/s over 150-m OM5 MMF, and the QAM-OFDM format at 224 Gbit/s in the BtB case have been achieved in 2021. For the high-level complex data-format transmission with rigorous demand of the signal-to-noise ratio (SNR), this work demonstrates the most up-to-date 32-ray quadrature amplitude modulation generalized frequency division multiplexing (32-QAM GFDM) data algorithm with optimized amplitude and K value for encoding the multimode (MM) VCSEL. To achieve the higher spectral-usage efficiency based on the SNR spectrum for maximal transmission data rate, the bit-loading discrete multi-tone (DMT) technique is implemented by rearranging each subcarrier to the appropriate QAM levels. By utilizing 32-QAM GFDM and bit-loading DMT, the maximal data rate in the back-to-back case could respectively achieve 119.5 Gbit/s and 130 Gbit/s when operating the MM VCSEL at 55 o C. After propagating through OM5 MM fiber (MMF), the transmission capacity of the VCSEL operated at 55 o C would decrease to 93.8 Gbit/s for 32-QAM GFDM and 83 Gbit/s for bit-loading DMT owing to the modal dispersion in OM5 MMF.

“…В силу поперечно-магнитной (ТМ) поляризации излучения в лазерах на межподзонных переходах, реализация поверхностного вывода излучения в квантово-каскадных лазерах (ККЛ) в конструкции микрорезонатора с распределенными брэгговскими резонаторами (в конструкции вертикально-излучающего лазера) невозможна [1][2][3]. В свою очередь формирование дифракционной решетки 2-го порядка позволяет реализовать поверхностно-излучающий ККЛ [4].…”

The results of studies of quantum-cascade laser with a surface emission through a grating formed in the layers of the top cladding of the waveguide by ion beam milling are presented. The active region of the QCL heterostructure was formed based on a heteropair of In0.53Ga0.47As / Al0.48In0.52As solid alloys with two-phonon resonance design. It is shown that lasing at room temperature close to 7.9 µm is demonstrated for a laser with a ring diameter of 191 µm. The mode spacing corresponds to whispering gallery modes.
