Electromagnetic localization and photonics

Journal of the Optical Society of America B, 1993
We show that characteristics of localized waves in nonabsorbing media, such as narrow resonances, giant transmission fluctuations, strong spatial correlation, and extreme sensitivity to variations in the dielectric function of the medium, may make possible a new class of compact filters, transducers, and switches.

Photonic band structure and symmetry properties of electromagnetic modes in photonic crystals

Physical Review E, 2007
Within the Maxwell framework and using a transfer-matrix technique we have determined a general equation which governs the photonic band structure and the density of states of one-dimensional superlattices composed of two alternate layers characterized by different refractive indexes, which may take on positive as well as negative values.

Vector potential quantization and the photon intrinsic electromagnetic properties: Towards nondestructive photon detection

International Journal of Quantum Information, 2017
We employ here the enhancement of the vector potential amplitude quantization at a single photon state. The analysis of the general solution of the vector potential, obtained by resolving Maxwell’s equations, implies that the amplitude is proportional to the angular frequency.

Electromagnetic Field and Photons

1984
The probabilistic treatment of the electromagnetic field in vacuum would have to be based on the results of Chapter 7 dealing with random fields. But the definition of a random field there proceeds, as should be the case in probabilistics, from the notion of a continuous concrete object regarded as the carrier of a field.

Electromagnetically induced one-photon and two-photon transparency in rubidium atoms

Optics Communications, 2003
Abstract We investigate electromagnetically induced transparency (EIT) for one-photon and resonant two-photon transitions in rubidium atomic vapors. One-photon transparency is obtained in the 5S–5P–5D three level ladder system. At the same time, we study electromagnetically induced transparency in the two-photon transition (EITT) from the 5S to the ...

Electromagnetic waves and photons

1996
This chapter discusses electromagnetic waves and photons. It begins by reviewing some basic ideas on the properties of waves, introducing the wave properties of radiation. There are several reasons for starting with a discussion of electromagnetic radiation. Historically, it was in this area that the quantum theory first developed.

Inverse Design Problems in Electromagnetics and Nano-Photonics

2005 Pacific Rim Conference on Lasers & Electro-Optics, 2006
In the Photonic Crystal field, we must now concentrate on the numerical solution of inverse design problems. There are a number of inverse algorithms, including genetic algorithms, the error-propagation method, and simulated annealing, that can contribute toward photonic crystal design.
