Optical signal processing using nonlinear periodic structures
Tim Ka Lung Wong
Written in English
Our analysis shows an unbalanced structure performs better in reflected intensity limiting, while a balanced structure performs better in transmitted intensity limiting. Based on the tradeoff between nonlinear grating strength and saturable absorption, we discover that there exists an optimum saturable absorption coefficient for maximum transmittance, reflectance and pulse compression for a given built-in grating structure (i.e. no linear grating, out-of-phase grating). We show pulse compression up to 50% and pulse stretching up to 20%.We present the first time-domain analysis of Gaussian pulse propagation through resonant nonlinear periodic structures with balanced and unbalanced nonlinear coefficients. The transmission and reflection propagation dynamics are thoroughly analyzed with varying nonlinear and linear grating strengths, pulse width, input intensity, saturable absorption, device length, and carrier lifetime for single and multiple pulses.

Optical Signal Processing Computing and Neural Networks Book Summary: In recent years, optical computing and optical neural networks research has enriched the field originally known as optical signal processing. Optical Signal Processing, Computing, and Neural Networks is a self-contained textbook that offers an introductory survey which examines photonics, linear and nonlinear signal.
Nonlinear optics (NLO) is the branch of optics that describes the behaviour of light in nonlinear media, that is, media in which the polarization density P responds non-linearly to the electric field E of the light. The non-linearity is typically observed only at very high light intensities (values of atomic electric fields, typically 10 8 V/m) such as those provided by lasers. 2. Signal Processing in Optical Fibers The spectrum of electromagnetic waves of interest for diﬀerent kinds of com-munication is shown in Figure 1. A typical communications system for using these waves to convey information is shown in Figure 2. This system assumes digitized information but is otherwiseFile Size: KB.
