Capella Teams with Boston University to Investigate the Practical Use of Quantum Photonics in ROADM Based Networks

Published: Mar 01, 2012

SAN JOSE, Calif.--(BUSINESS WIRE)--Capella, the leading provider of wavelength selective switch (WSS) technologies for use in reconfigurable optical add/drop multiplexer (ROADM) and optical cross connects, has today announced the successful completion of a demonstration of quantum photonic techniques to evaluate the Polarization Mode Dispersion (PMD) of complex optical devices. Capella’s CRx WSS product platform served as an ideal test device for measurement of PMD during the demonstration due to the extremely low PMD of Capella’s CRx product. The demonstration, using quantum interferometry with broadband polarization-entangled states, is the culmination of research work completed by Boston University’s Quantum Communication and Measurement Laboratory (QCML) led by Professor Alexander Sergienko and funded by Capella. This research highlights the high-resolution measurements made possible by quantum photonic techniques and validates the benefit of collaboration between industry leaders, such as Capella, and university research teams.
