Latest Patents

Douglas Butler holds a patent for "Continuously tunable optical dispersion compensation synthesizers using cascaded etalons." This patent describes a method for designing individual stages of a multiple cascaded etalon TDC device. The method allows for continuous thermo-optic tuning over a desired range without inducing incremental signal distortion due to uncontrolled and unpredictable dispersion during tuning. This innovation ensures that signals can transmit without encountering periods of incremental distortion or dark spots. The method incorporates prior knowledge of each etalon stage, after full assembly, for spectral group delay profile as a function of temperature through modeling and/or characterization. Characterization can account for performance variations that arise from allowed manufacturing tolerances.
