Resonance in Layered Bragg Structures
#Matlab #Physics #Mathematics
One of the most important technical applications of nonlinear material properties is to create logical devices, memory devices and data processing devices based on the hysteresis phenomenon. An actual problem for the development of modern information technology is the realization of such devices in the terahertz frequency range, and to increase performance while reducing size and weight.
Using the Bragg reflectors for strong frequency-selective feedback in Fabry-Perot resonator allows us to observe multistability with less thickness of the nonlinear layer. In most cases, the exact solution of the problem of electromagnetic field distribution on the boundary of the layered Bragg structure with Kerr nonlinear layers can not be found, and we have to use approximate numerical methods.
The proposed method allows us to investigate the resonance properties of structures with different combinations of nonlinear layers, including Bragg structures containing layers with several types of Kerr nonlinearity. The choosing of inclusion points of lumped nonlinear elements is a flexible tool to achieve the desired multistable frequency and amplitude characteristics.
