Principles and practicePrentice Hall Europe B 21 8 Appathuraiand P. December 2, Published: The group delay of the device under test is directly obtained from the instantaneous frequency of a short optical pulse after propagation in the device, itself obtained with temporal and spectral interferometry.
Temporal and spectral fringe encoding provide excellent accuracy and resistance to noise, and a wide variety of dispersions can be characterized even at high insertion losses. OSA will be closed for the holidays from 21 December Click here to learn more.
