【Abstract】 Multi-layer GTI type optical all-pass filter, as a novel kind of photonic device, is analyzed simply. On the basis, a formula for the devise of GTI-OAPF is given. As numerical examples, the group delay spectra of some kinds of periodic film layers and multi-cavity GTI-OAPF have been computed. The possibility of this optical device used for multi-channel group-delay dispersion compensation is discussed.更多还原
