In this article numerical methods used to model photonic devices are presented. In particular, the governing equations describing the problem, the coupling between electrical and optical fields, and the numerical algorithms used for computing solutions are discussed. As a computational example, we present the modeling of a semi-conductor optical amplifier employed as an all-optical demultiplexer.

In these lectures we dwell upon the cosmological cornerstones of the Very Early Universe (VEU) theory: Parametric Amplification Effect (PAE) responsible for the generation of Pri

In this paper, new upper and lower bounds are proposed for the capacity of discrete-time Laguerre channel. Laguerre behavior is used to model vorious types of optical systems and networks such as optical amplifiers, short distance visible light communication systems with direct detection and coherent code devision multiple access (CDMA) networks. Bounds are derived for short distance visible li...
