Paper Abstract

A method for accurately measuring the coupling ratio of single mode fiber directional couplers is described. The method is insensitive to source fluctuations and eliminates the need for calibrated detectors. Accuracies of ± 0.50% have been demonstrated. The dependence of coupling ratio on input polarization state can also be measured using the technique. Measured coupling ratios on a sample quantity of 20 commercially-available couplers are compared to vendor specifications.
