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

Abstract : 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.
