The parameters of pulses reflected from non-periodic Bragg layered structures have been investigated. The specific structures such as asymmetric resonators with periodic Bragg reflectors and structures with chirp variation of the thickness of the “period” have been examined. The numerical investigations have been made both in Bragg band and outside it. The frequency characteristics of the structures...
The behavior of quasi-periodic and aperiodic (chirp) Bragg structures with thin lossy layers was examined. In order to determine the frequency dependence of the reflection coefficient transmission matrix method was used. A deep minimum of the reflection coefficient for any frequency is implemented by proper choice of the thickness of the last thin film and its optical distance to the substrate. The...
