High-speed vertical-cavity surface-emitting lasers (VCSELs) at different wavelengths present the backbone of high speed optical links showing large bandwidth density. The state of the art of present designs of VCSELs is summarized, including driving conditions. Several novel approaches for the design of GaAs-based VCSELs and VCSEL arrays are reported, potentially leading e.g. to lower power consumption, much larger single mode output and larger bandwidth. The first one is based on using the photon lifetime as a system sensitive optimization parameter. The second one reports for the first time details of a disruptively novel (patented) design based on oxidizing the apertures from multiple etched holes in varying arrangements and finally on multi-aperture designs in one device. These designs are essential for improving the energy-efficiency of modules by optimizing the interplay of electronic driver and photonic device.

“…Other interesting applications involve VCSELs for 3D gesture and face recognition or for automotive purposes, such as LiDAR (Laser Imaging Detection and Ranging) for autonomous driving [5]. In particular, VCSELs are already the dominant optical sources for optical links in datacenters and high-performance computers [6][7][8][9].…”

Reduced Dimensionality Multiphysics Model for Efficient VCSEL Optimization

The ICT scene is dominated by short-range intra-datacenter interconnects and networking, requiring high speed and stable operations at high temperatures. GaAs/AlGaAs vertical-cavity surface-emitting lasers (VCSELs) emitting at 850–980 nm have arisen as the main actors in this framework. Starting from our in-house 3D fully comprehensive VCSEL solver VENUS, in this work we present the possibility of downscaling the dimensionality of the simulation, ending up with a multiphysics 1D solver (D1ANA), which is shown to be capable of reproducing the experimental data very well. D1ANA is then extensively applied to optimize high-temperature operation, by modifying cavity detuning and distributed Bragg’s reflector lengths.

“…Note that the impact of chromatic dispersion, which is generally important in RoF links based either on MTMV (due to the multi‐wavelength transmission [16, 17]) or on DFB (due to the high level of adiabatic chirp [18–20]) is mitigated in the presented case by the use of SMV.…”

To decrease cost and consumption of future wireless infrastructures, radio-over fibre systems utilising 850 nm vertical cavity surface emitting lasers and standard single-mode fibre (SSMF) are deserving particular attention in replacing the typical use of graded-index multimode fibre (GI-MMF). In the present work, a characterisation of noise and non-linearities of these links is performed, followed by an estimation of their impact on the system dynamics and the quality of the received signal. This allows to show that very good and similar performances can be obtained through the utilisation of SSMF and GI-MMF for the transmission of five long-term evolution channels with 20 MHz bandwidth, confirming that the former, by the higher diffusion and lower cost per metre of the SSMF, can be put among the leading candidates for the realisation of fourth-generation (4G) and 5G wireless networks.
