Optimization of the Mode-Dependent Signal Delay Method for the Measurement of Modal Dispersion

The mode-dependent signal delay method can be used to estimate the modal dispersion vector of multimode fibers. We compute optimal launch modes minimizing the noise error in this estimate. The electronic SNR is improved asymptotically by almost 6 dB compared to conventional mode combinations.
