... on whether (k 2 n i2 − β 2 ), i = 1, 2, 3, is greater than or less than zero. Of course, E(x, y) and ∂E(x, y)/∂x must be continuous at the interface between layers. Hence the possible modes are limited to those shown in Fig. 2.2. Consider how the mode shape changes as a function of β, for the case o ...

... out in [26] and [27]. When an electron is captured by a defect level with a subsequent capture of a hole, multiphonon emissions occur [28]–[30]. This will result in strong vibration of the defect atoms and reduce the energy barrier for the defect motion such as migration, creation, or clustering. Us ...

Module P6.4 Optical instruments
... The function of optical instruments is to extend the performance of the human eye in a variety of ways. For example, we may need to magnify the view of an object, if it is too small (using a microscope) or if it is very far away (using a telescope), or we may need a permanent record (obtained using ...

Spectroscopy – I. Gratings and Prisms
... If we could see the whole spectrum (radio to γ–ray), then every order would completely overlap with every other order. In reality, of course, many effects limit what we can see/measure. For example, the atmosphere will eliminate most photons at shorter wavelengths than about 340nm – as well as large ...
