The critical role of substrates in mitigating the power-efficiency trade-off in near-field thermophotovoltaics
Kartika N. Nimje, Julien Legendre, Michela F. Picardi +2
Near-field thermophotovoltaic systems can achieve ultra-high power densities, however, this often comes at the cost of reduced efficiency. We show that this power-efficiency trade-…
Bulk-to-surface coupling of spatiotemporal vortices
Francisco J. RodrÃguez-Fortuño, Michela F. Picardi, Konstantin Y. Bliokh
We consider the coupling of bulk space-time-structured waves, such as spatiotemporal vortex pulses (STVPs), to surface waves, such as surface plasmon-polaritons (SPPs). For resonan…
Fundamental limitations of thermoradiative energy conversion
Maxime Giteau, Michela F. Picardi, Georgia T. Papadakis
Understanding the fundamental limits of various energy conversion approaches is essential for assessing their efficiency and power output. In this work, we derive general performan…
Mid-IR chirality and chiral thermal emission through twisting
Michael T. Enders, Mitradeep Sarkar, Evgenia Klironomou +4
Chirality in the mid-infrared spectral range plays a crucial role across physical, chemical, and biological sciences, yet sources of chiral infrared light do not currently exist. T…
