“…This could be done using a detector matrix, which is then compared to a prepared numerical dictionary of matrices to extract the correct signal. A more sophisticated implementation could use a specialized detector that takes advantage of the circular symmetry of the OAM beam [39] .…”

Data centers are crucial elements in modern information technology. In order to implement the next generation of data centers, new challenges must be overcome. These include reducing the energy consumption, increasing the data rates, reducing the communication latency, increasing the flexibility and scalability, and reducing the maintenance time and cost. One promising way for meeting these challenges is to employ multichannel optical wireless communication as part of the data center hybrid communication network. In this paper, we analyze three technologies that could be used in this context: MIMO (Multiple-in-Multipleout), multiplexing through orbital angular momentum of light, and direct modulation through the large number of modes associated with orbital angular momentum. Our results indicate that these technologies could provide an innovative and flexible means of meeting the challenges of the next generation of data centers.

“…1,2 In particular, light carrying orbital angular momentum (OAM) different from zero has been used in many applications ranging from quantum simulation 3,4 and quantum engineering 5,6 to quantum and classical communications. [7][8][9][10][11][12][13][14] Recently, OAM modes have been particularly studied for their uses in biomedical applications of imaging and diagnosis. [15][16][17] In particular, they have been exploited for the development of noninvasive diagnostics on tissues.…”

Scattering phenomena affect light propagation through any kind of medium from free space to biological tissues. Finding appropriate strategies to increase the robustness to scattering is the common requirement in developing both communication protocols and imaging systems. Recently, structured light has attracted attention due to its seeming scattering resistance in terms of transmissivity and spatial behavior. Moreover, correlation between optical polarization and orbital angular momentum (OAM), which characterizes the so-called vector vortex beams (VVBs) states, seems to allow for the preservation of the polarization pattern. We extend the analysis by investigating both the spatial features and the polarization structure of vectorial optical vortexes propagating in scattering media with different concentrations. Among the observed features, we find a sudden swift decrease in contrast ratio for Gaussian, OAM, and VVB modes for concentrations of the adopted scattering media exceeding 0.09%. Our analysis provides a more general and complete study on the propagation of structured light in dispersive and scattering media.

“…In order to achieve a high data rate, a straightforward system with simple logic is preferable to a complex detector system. In our system, we have tried to employ well known technology that is already being used [38]. A circular detector is also an interesting alternative, and may be of interest for this system [39].…”

Vortex light beams can provide a tremendous alphabet for encoding information. We derive a symbol decoding algorithm for a direct detection matrix detector vortex beam receiver using Laguerre Gauss (LG) modes, and develop a mathematical model of symbol error rate (SER) for this receiver. We compare SER as a function of signal to noise ratio (SNR) for our algorithm and for the Pearson correlation algorithm. To our knowledge, this is the first comprehensive treatment of a decoding algorithm of a matrix detector for an LG receiver.
