Universal Optimal Transmission of Light Through Disordered Materials

Universal optimal transmission of light through disordered materials.

We experimentally demonstrate increased diffuse transmission of light through strongly scattering materials. Wave front shaping is used to selectively couple light to the open transport eigenchannels, specific solutions of Maxwell's equations which the sample transmits fully, resulting in an increase of up to 44% in the total angle-integrated transmission compared to the case where plane waves ...

Supplemental Online Material for ‘ Universal optimal transmission of light through disordered materials ’

In the accompanying Letter we show an experiment where the wavefront of incident light is shaped to excite open eigenchannels, and we demonstrate an increased total transmission through an opaque, strongly scattering sample. Our wavefront shaping algorithm maximizes the intensity in a target point behind the sample. Ideally, the algorithm constructs the wavefront for which the intensity transmi...

Correlations in Transmission of Light through a Disordered Amplifying Medium

The angular and frequency correlation functions of the transmission coefficient for light propagation through a strongly scattering amplifying medium are considered. It is found that just as in the case of an elastic scattering medium the correlation function consists of three terms. However, the structure of the terms is rather different. Angular correlation has a power-law decay and exhibits ...

Light Transmission through Three Types of Translucent Zirconia

  Objective: Zirconia cores have limited light transmittance and data are scarce on light transmission through zirconia cores with and without the veneering ceramic.   Methods: In this in vitro study, Disc-shaped specimens (11.5 mm in diameter and 0.4 (0.05) mm in thickness) were fabricated of three types of zirconia namely Mamut, Heany and ZirkonZahn (n=5). A disc-shaped specimen (11.5 mm in d...
