Photon Diffusion in Microscale Solids
Avijit Das, Andrew K. Brown, Merlin L. Mah +1
This paper presents a theoretical and experimental investigation of photon diffusion in highly absorbing microscale graphite. An Nd:YAG continuous wave (CW) laser is used to heat t…

Enhanced absorption per unit mass for infrared arrays using subwavelength metal-dielectric structures
Avijit Das, Joseph J. Talghader
The absorption to mass ratio of the infrared arrays is enhanced to approximately 1.33 to 7.33 times larger than the previously reported structures by incorporating two design chara…

The decomposition of aberrated or turbulent wavefronts into a spatial mode spectrum using optical cavities
Merlin L. Mah, Joseph J. Talghader
It is shown that an aberrated wavefront incident upon a Fabry-Perot optical cavity excites higher order spatial modes in the cavity, and that the spectral width and distribution of…
