Fabry-Perot model

To demonstrate the method an example of a slow-wave optical structure is modelled. Such structures consist of a cascade of directly coupled optical resonators in order to enhance the nonlinear effects. The structure used here was recently defined within Working Group 2 of the European Action COST Pll (http //w3.uniromal.it/energetica/slow waves.doc). One period of the structure consists of one-dimensional Fabry-Perot cavity placed between two distributed Bragg reflectors (DBR) and can be described by the sequence... 

A simple model that makes it possible to describe optical bistability in a variety of systems is a plane nonlinear Fabry-Perot interferometer, filled with a medium whose refractive index is intensity dependent [106]. The slow kinetics of a... 

Several comprehensive models for the emission of dipoles in a multilayer structure have been presented in the literature, which take into account the orientation of dipoles in the emitting layer (Bjork, 1991). Less elaborated expressions for the emission of a thin-film structure with an emitting layer can also be developed using an approach similar to the one presented by Smith for describing the transmittance of Fabry-Perot structures, using the concept of effective interfaces (Smith, 1958). We used this approach to obtain the following expression for bottom-emission OLEDs (similar to other expressions that can be found in the literature, for example Lee et al., 2002) ... 

This chapter provides the general theories and discussions of optical sfruc-tures and characteristics of OLEDs. To start with, it presents a simple and analytical formulation of microcavity effects in OLEDs based on the concepts of the Fabry-Perot cavity this provides a clearer physical insight but is more limited in its description of the effects of microcavity. Subsequently, this chapter provides a brief description of rigorous electromagnetic modeling of optical characteristics of OLEDs. These notions are then used as the... 

In the case of very thin samples in transmission measurements, Fabry-Perot interference fringes can arise as a result of sample-support interactions which can manifest as an oscillatory signal that convolutes the data and further complicates the data interpretation process. Though proper modeling of these feamres can produce the tme absorbance while also revealing additional information about the sample, a workaround is to utilize a diffuse reflectance or absorption configuration as detailed below. 

In this paper, optical techniques (Fabry Perot and self beating correlation) are first described and used to measure the viscoelastic parameters of 5P4E as a function of the pressure and temperature. These results represent an extension of the data available in the literature. Then, various rheological models for fluids behaviour in an elastohydrodynamic contact (E.H.D.) are described.

The short-wavelength interferometer has a Bragg stack consisting of Oxide2 trapped between Polyl and Poly2 for the top reflector.
