Photonic density of states maps for design of photonic crystal devices

Abstract

In this work, it has been investigated whether photonic density of states maps can be applied to the design of photonic crystal-based devices. For this reason, comparison between photonic density of states maps and transmittance maps was carried out. Results of comparison show full correspondence between these characteristics. Photonic density of states maps appear to be preferable for the design of photonic crystal devices, than photonic band gap maps presented earlier and than transmittance maps shown in the paper.Comment: 5 pages, 6 figure

Radiative decay engineering 6: Fluorescence on one-dimensional photonic crystals

“…There have been some important contributions to sensing using PCs [34-36]. The local radiative optical density of states (LRDoS) increases near the edge of a PBG and then becomes smaller and approaches zero at the PBG [37-38]. As will be described in the Discussion below it is preferable to consider the local radiative density of the state (LRDoS) which takes into account the dipole location and orientation.…”

Comparative analysis of PBG and PhDOS maps for precise design of the photonic crystal devices

“…In the work [2], there were proposed the PhDOS maps. Such characteristics provide the information about the PhC behavior outside the PBG.…”

“…In the works [1] and [2] there were given the investigation of photonic crystals (PhC) parameters using the analysis of photonic band gap (PBG) and photonic density of states (PhDOS) maps. In our current work, we have studied the efficiency of these two methods by the comparison of their computation speed as well as the accuracy provided by these two methods.…”

Distribution of reflection spectrum for the photonic‐crystal structure of Morpho butterfly wing under oblique incidence

“…The RCWA method is a useful tool to analyse the reflection properties of the periodic structure, and the PWE method is adopted to calculate the band diagram and PhDOS of the Morpho butterfly wing structure. Then, the PhDOS can be used to represent the optical transmittance [18][19][20]. PhDOS is a suitable method to analyse the Morpho butterfly wing because the reflection mechanism may not be dominated by the partial band gap.…”
