Pre-fractal multilayer structure for polarization- insensitive temporally and spatially coherent thermal emitter

Opt Express. 2013 May 6:21 Suppl 3:A576-84. doi: 10.1364/OE.21.00A576.

Abstract

We investigate electromagnetic wave propagation through one-dimensional stacks arranged as truncated pre-fractal Cantor multilayer. Taking into account materials' dispersion as well as real absorptive losses, we studied the spectral and spatial emissivity in both on-axis and off-axis direction. The typical cavity mode resonances associated to the pre-fractal structure are exploited to design a polarization-insensitive infrared emitter pertaining both temporal and spatial coherence.
