Coherent Thermal Emission from Large-Scale Suspended Nanomechanical Membranes
Mitradeep Sarkar, Rajashree Haldankar, Julien Legendre +3
Thermal radiation is an abundant form of incoherent light. Generating coherent infrared light through incandescence promises a cheap alternative to the costly and epitaxially compl…
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…
Design of narrowband infrared emitters by hybridizing guided-mode resonance structures with van der Waals materials
Mehrdad Shokooh-Saremi, Maxime Giteau, Mitradeep Sarkar +1
In this paper, narrowband emitters have been designed using particle swarm optimization (PSO) in the 10-20 μm infrared range. The device structure consists of an anisotropic α-MoO3…
Deep-subwavelength Phase Retarders at Mid-Infrared Frequencies with van der Waals Flakes
Michael T. Enders, Mitradeep Sarkar, Aleksandra Deeva +5
Phase retardation is a cornerstone of modern optics, yet, at mid-infrared (mid-IR) frequencies, it remains a major challenge due to the scarcity of simultaneously transparent and b…
Retrieving optical parameters of emerging van der Waals flakes
Mitradeep Sarkar, Michael T. Enders, Mehrdad Shokooh-Saremi +5
High-quality low-dimensional layered and van der Waals materials are typically exfoliated, with sample cross sectional areas on the order of tens to hundreds of microns. The small…
Maximal Violation of Kirchhoff's Law in Planar Heterostructures
Lu Wang, F. Javier García de Abajo, Georgia T. Papadakis
Violating Kirchhoff's law has so far required nonreciprocal materials patterned in microstructures. In these configurations, the excitation of a guided or polaritonic mode that lie…
