Applied Optics | 2011

Optimal design for 100% absorption and maximum field enhancement in thin-film multilayers at resonances under total reflection

Césaire N'Diaye; Fabien Lemarchand; Myriam Zerrad; Dominique Ausserré; Claude Amra

Dielectric optical coatings are designed at resonances to reach total absorption, whatever the low value of the imaginary index. The corresponding field enhancement within the stack can be arbitrarily increased with the optimization procedure. Applications concern optical sensors and threshold lasers.


Optical Interference Coatings (2013), paper TD.5 | 2013

Multidielectric structures designed for giant optical field enhancement

Myriam Zerrad; Césaire N'Diaye; A. L. Lereu; Fabien Lemarchand; Claude Amra

Multidielectric coatings are designed to reach total absorption & maximum field enhancement at resonances. The method is analytic and numerical results are given. We study transition to plasmonic devices then scattering data for enhancement measurement.


Imaging and Applied Optics Technical Papers (2012), paper OTu4D.7 | 2012

Multi-dielectric structured components for giant optical field enhancement: an optimization process

Césaire N'Diaye; Myriam Zerrad; Fabien Lemarchand; Michel Lequime; Claude Amra

Multidielectric coatings are designed to reach total absorption and maximum field amplification at resonances. The design method is analytic, numerical results are given. Comparison with plasmons is detailed. Scattering behavior is investigated for amplification measurement.
