TLDR
In this article, the optical properties of a one-dimensional (1D) photonic heterostructure with graded-index nonlinear materials are analyzed theoretically and the influence of the gradation profile of the nonlinear layers on the linear and nonlinear responses of the structure is analyzed.Abstract:
The optical properties of a one-dimensional (1D) photonic heterostructure with graded-index nonlinear materials are demonstrated theoretically. The influence of the gradation profile of the graded-index nonlinear layers on the linear and nonlinear responses of the structure are analysed. It is shown that the Q-factor of the defect mode and the threshold input intensity to achieve the optical bistability in the used photonic heterostructure depend on the gradation profile of the graded-index nonlinear layers.read more

Localization of optics: Quasiperiodic media.
TL;DR: An experiment to probe the (quasi)localization of the photon is proposed, in which optical layers are constructed following the Fibonacci sequence, which has scaling with respect to the number of layers, as well as an interesting fluctuation.

Omnidirectional gap and defect mode of one-dimensional photonic crystals containing negative-index materials
TL;DR: In this paper, it was shown that a one-dimensional photonic crystal containing a negative-index material has an omnidirectional gap, owing to the mechanism of zero (volume) averaged refractive index.
