Quantum effects in non linear optics

2007 Quantum Electronics and Laser Science Conference, 2007
Optical non linear interactions changing the statistics of a light field are often counteracted by dissipative processes. Artificial structuring of the non linear medium can reduce dissipation and enhance the effect of the non linearity.

Equalization of non-linear optical channels

ICC '98. 1998 IEEE International Conference on Communications. Conference Record. Affiliated with SUPERCOMM'98 (Cat. No.98CH36220), 2002
This paper presents a comparative analysis of various linear and nonlinear equalizers for a high density optical channel. Since the read-out process is nonlinear, a suitable model based on the Volterra series has been adopted. We compare the performance and complexity of equalizers designed for linear and nonlinear channels.

Non-linear Optics

Contemporary Physics, 1964
Abstract It is shown that non-linear optical phenomena will occur when high intensity light beams interact with matter. Such light beams have become available with the invention of lasers. A review of the experiments performed with lasers to exhibit non-linear effects is given.

Electron crystallography and non-linear optics

Microscopy Research and Technique, 1999
Electron crystallography can be used to obtain specific information about molecular parameters such as the polarisability, dipole moment, and hyperpolarisability. In this, work we show how a combination of quantum mechanics and simulation methods can be used to solve several unknown organic structures and how the calculated molecular parameters can be ...

Non-linear Optics

1970
We have assumed in previous chapters that the electric current density and polarization in a medium are linear functions of the electric field of an electromagnetic wave. The linear optical properties are defined in terms of these functions. The justification for the linear theory is that the applied field is much less than the atomic fields which act ...

Non‐Linear Optical Transmission Systems

European Transactions on Telecommunications, 1993
AbstractIn recent years much research has focussed on the development of high capacity optical transmission systems for terrestrial and undersea application. The development of optical amplifier repeaters has led to the situation where multigigabit transmission is required over very large distances.
