Multi-resonant silver nano-disk patterned thin film hydrogenated amorphous silicon solar cells for Staebler-Wronski effect compensation
Ankit Vora, Jephias Gwamuri, Joshua M. Pearce +2
We study polarization independent improved light trapping in commercial thin film hydrogenated amorphous silicon (a-Si:H) solar photovoltaic cells using a three-dimensional silver…
Light transport in PT-invariant photonic structures with hidden symmetries
M. H. Teimourpour, R. El-Ganainy, A. Eisfeld +2
We introduce a recursive bosonic quantization technique for generating classical PT photonic structures that possess hidden symmetries and higher order exceptional points. We study…
Exchanging Ohmic Losses in Metamaterial Absorbers with Useful Optical Absorption for Photovoltaics
Ankit Vora, Jephias Gwamuri, Nezih Pala +3
Using metamaterial absorbers, we have shown that metallic layers in the absorbers do not necessarily constitute undesired resistive heating problem for photovoltaics. Tailoring the…
Exceptional points and lasing self-termination in photonic molecules
Ramy El-Ganainy, Mercedeh Khajavikhan, Li Ge
We investigate the rich physics of photonic molecule lasers using a non-Hermitian dimer model. We show that several interesting features, predicted recently using a rigorous steady…
Supersymmetric mode converters
Matthias Heinrich, Mohammad-Ali Miri, Simon Stützer +4
Originally developed in the context of quantum field theory, the concept of supersymmetry (SUSY) can be used to systematically design a new class of optical structures. In this wor…
