Enhanced Absorption in thin and ultrathin silicon films by 3D photonic band gap back reflectors
Devashish Sharma, Shakeeb B. Hasan, Rebecca Saive +2
Since thin-film silicon solar cells have limited optical absorption, we explore the effect of a nanostructured back reflector to recycle the unabsorbed light. As a back reflector w…
The local density of optical states in the 3D band gap of a finite photonic crystal
Charalampos P. Mavidis, Anna C. Tasolamprou, Shakeeb B. Hasan +5
A three-dimensional (3D) photonic band gap crystal is an ideal tool to completely inhibit the local density of optical states (LDOS) at every position in the crystal throughout the…
Three-dimensional photonic band gap cavity with finite support: enhanced energy density and optical absorption
D. Devashish, Oluwafemi Ojambati, Shakeeb B. Hasan +2
We study numerically the transport and storage of light in a 3D photonic band gap crystal doped by a single embedded resonant cavity. The crystal has finite support since it is sur…
Reflectivity calculated for a 3D silicon photonic band gap crystal with finite support
D. Devashish, Shakeeb B. Hasan, J. J. W. van der Vegt +1
We study numerically the reflectivity of three-dimensional (3D) photonic crystals with a complete 3D photonic band gap, with the aim to interpret recent experiments. We employ the…
