Few Mode Transmission Fiber With Low DGD, Low Mode Coupling, and Low Loss

A transmission fiber for mode division multiplexing supporting LP <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">01</sub> and LP <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sub> modes, with low differential group delay, low mode coupling, and low loss for both modes is presented. Spatially and spectrally resolved mode imaging (S <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> imaging) is used for characterization.
