title: Monomode-polarization-maintaining fiber directional couplers.
abstract: The fabrication and experimental evaluation of monomode-fiber directional couplers having polarization-maintaining elliptical-cored fibers is described. The couplers have a polarization isolation of greater than 40 dB and insertion losses of less than 0.5 dB.
