SI-Traceable Calibration and Performance Benchmarking of a Terahertz Photomixer Transmitter-Receiver System Using a Rydberg Atomic Sensor
Alisher Duspayev, Kaitlin R. Moore, Georg Raithel +1
Accurate calibration of electromagnetic field strength in the terahertz (THz) frequency regime remains challenging due to the limited availability of SI-traceable field sensors. He…
Effects of inert background gases and photo-illumination on three-color electromagnetically induced transparency of rubidium vapor
Alisher Duspayev, Bineet Dash, Georg Raithel
Three-color Rydberg electromagnetically induced transparency (EIT) of room-temperature Rb vapor in the presence of inert gases (Ar, Ne, and N) at 50~mTorr and 500~mTorr is inve…
