Contactless Continuous-Variable Quantum Optical State Conditioning With Classical MmWave Phase
Niloy Ghosh, Sarang Pendharker
This paper establishes the Heisenberg's picture framework for seamless mmWave-to-photonic data transduction. Based on this framework, contactless modulation of continuous-variable…
Photonic-Spin governed absorption in a mu-near-zero subwavelength gyromagnetic cylinder
Rajarshi Sen, Sarang Pendharker
Realizing non-reciprocal scattering and absorption from subwavelength elements has several applications across the electromagnetic frequency spectrum. Here we show that gyromagneti…
Encoding quantum phase-space with classical wireless microwave constellation
Niloy Ghosh, Sarang Pendharker
This paper develops a theoretical framework for enabling seamless transfer of digital information from classical microwave domain to the quantum optical domain in wireless-to-optic…
Poynting Vector Spin in Gyromagnetic Medium and its Impact on Backward Power Flow in Waveguiding Structures
Rajarshi Sen, Sarang Pendharker
This paper investigates the reactive power and spin of instantaneous Poynting vector in the bulk of gyromagnetic medium. It is shown that the gyromagnetic medium introduces a spin…
Spin-governed topological surfaces and broken spin-momentum locking in a gyromagnetic medium
Rajarshi Sen, Sarang Pendharker
Topology of isofrequency surfaces plays a crucial role in characterizing the interaction of an electromagnetic wave with a medium. Thus, engineering the topology in complex media i…
Thermal graphene metamaterials and epsilon-near-zero high temperature plasmonics
Sarang Pendharker, Huan Hu, Sean Molesky +7
The key feature of a thermophotovoltaic (TPV) emitter is the enhancement of thermal emission corresponding to energies just above the bandgap of the absorbing photovoltaic cell and…
PT-symmetric spectral singularity and negative frequency resonance
Sarang Pendharker, Yu Guo, Farhad Khosravi +1
Vacuum consists of a bath of balanced and symmetric positive and negative frequency fluctuations. Media in relative motion or accelerated observers can break this symmetry and pref…
Axial Super-resolution Evanescent Wave Tomography
Sarang Pendharker, Swapnali Shende, Ward Newman +3
Optical tomographic reconstruction of a 3D nanoscale specimen is hindered by the axial diffraction limit, which is 2-3 times worse than the focal plane resolution. We propose and e…
Universal Zero Conductivity Condition for Optical Absorption
Yu Guo, Sarang Pendharker, Zubin Jacob
Harnessing information and energy from light within a nanoscale mode volume is a fundamental challenge for nanophotonic applications ranging from solar photovoltaics to single phot…
