Nonreciprocal Thermophotonic Cooling
Daniel Cui, Parthiban Santhanam, Aaswath P. Raman
Solid-state cooling via electroluminescent emission from light-emitting diodes is a promising alternative to thermoelectric and vapor-compression refrigeration, but practical perfo…
Directional Thermal Emission Across Both Polarizations in Planar Photonic Architectures
David E. Abraham, Daniel Cui, Baolai Liang +5
Directional and spectral control of thermal emission is essential for applications in energy conversion, imaging, and sensing. Existing planar, lithography-free epsilon-near-zero (…
Chip-scale monolithic optoelectronic voltage boost conversion
Parthiban Santhanam, Daniel Cui, Jae Seung Hwang +4
Voltage conversion is a fundamental electronic process critical to engineered systems across a wide spectrum of applications and spanning many orders of magnitude in scale. Convent…
High-Performance Photonic Transformers for DC Voltage Conversion
Bo Zhao, Sid Assawaworrarit, Parthiban Santhanam +2
Direct current (DC) converters play an essential role in electronic circuits. Conventional high-efficiency DC voltage converters, especially step-up type, rely on switch-mode opera…
Controlling the dopant profile for SRH suppression at low current densities in 1330nm GaInAsP light-emitting diodes
Parthiban Santhanam, Wei Li, Bo Zhao +5
The quantum efficiency of double hetero-junction light-emitting diodes (LEDs) can be significantly enhanced at low current density by tailoring the spatial profile of dopants to su…
Thermodynamic Limits of Energy Harvesting from Outgoing Thermal Radiation
Siddharth Buddhiraju, Parthiban Santhanam, Shanhui Fan
We derive the thermodynamic limits of harvesting power from the outgoing thermal radiation from the ambient to the cold outer space. The derivations are based on a duality relation…
