Abstract(in Japanese) (See Japanese page)
Abstract(in English) Least mean square fitting (LMSF) method is applied to the first-order differential group delay (DGD) analysis especially concerning the optical components. Based on the conventional polarimetric methods, some drawbacks for the small DGD measurements are discussed. Then the application of the LMSF to the Poincare sphere method is presented. The minor change of the conventional method will result the significant enhancement for the DGD evaluation. Angular velocity of the Stokes vector variance with respect to the optical wavelength is evaluated to provide the DGD of the device under test (DUT). Enhancement of the precision of the DGD evaluation is expected since the measurement times of the state of polarization (SOP) is decreased in each wavelength and also relatively simple calculation scheme is used. Comparison of the DGD evaluation results of the LMSF with those of the Jones matrix eigenanalysis are presented after measurements of an optical circulator and a bandpass filter whose full-width of the half-maximum is 0.8nm.
