A Fiber Measurement System with Approximate Deconvolution Based on the Analysis of Fault Clusters in Linearized Bregman Iterations
Yuneisy Garcia Guzman, Felipe Calliari, Gustavo C. Amaral +1
Automatic detection of faults in optical fibers is an active area of research that plays a significant role in the design of reliable and stable optical networks. A fiber measureme…
Entanglement and non-locality between disparate solid-state quantum memories mediated by photons
Marcel. li Grimau Puigibert, Mohsen Falamarzi Askarani, Jacob H. Davidson +7
Entangling quantum systems with different characteristics through the exchange of photons is a prerequisite for building future quantum networks. Proving the presence of entangleme…
Characterization of Depolarizing Channels Using Two-Photon Intereference
Gustavo C. Amaral, Guilherme P. Temporão
Depolarization is one of the most important sources of error in a quantum communication link that can be introduced by the quantum channel. Even though standard quantum process tom…
Alignment-free characterization of polarizing beamsplitters
Felipe Calliari, Pedro Tovar, Christiano Nascimento +3
Traditional methods for measurement of Polarizing Beamsplitter (PBS) parameters, especially the extinction ratio, require highly polarized light sources, alignment procedures and/o…
Full Optical Fiber Link Characterization with the BSS-Lasso
Raphael Saavedra, Pedro Tovar, Gustavo C. Amaral +1
Manipulation of the detected backscattered Rayleigh signal inside the bandwidth of a frequency-swept optical sub-carrier propagating into an optical fiber permits an efficient loca…
Linearized Bregman Iterations for Automatic Optical Fiber Fault Analysis
Michael Lunglmayr, Gustavo C. Amaral
Supervision of the physical layer of optical networks is an extremely relevant subject. To detect fiber faults, single-ended solutions such as the Optical Time Domain Reflectometer…
