REFERENCE ARTIFACT FOR OPTICAL GROUP DELAY AND CHROMATIC DISPERSION

摘要

The reference artifact has an amplitude response that includes an attenuation line having an extremum at a center frequency. The reference artifact has either or both of a calibrated optical group delay and a calibrated chromatic dispersion at a calibration frequency in a calibration frequency range that extends about the center frequency. One or both of optical group delay and chromatic dispersion are measured by providing a reference artifact. The reference artifact has an amplitude response that includes an attenuation line having an extremum at a center frequency. Either or both of the optical group delay and the chromatic dispersion of the reference artifact is calibrated at a calibration frequency in a calibration frequency range that extends about the center frequency.
