We demonstrate an atomic radio-frequency (RF) receiver and spectrum analyzer based on thermal Rydberg atoms coupled to a planar microwave waveguide. use off-resonant RF heterodyne technique achieve continuous operation for carrier frequencies ranging from DC 20 GHz. The system achieves intrinsic sensitivity of up -120(2) dBm/Hz, coupling, 4 MHz instantaneous bandwidth, over 80 dB linear dynamic...

There are two popular approaches to the design of a polarimetric radiometer: using either coherent or incoherent detection. Coherent detection implies that a direct cross-correlation is performed of the vertical and horizontal components of the incident electrical field. Incoherent detection derives the third and fourth Stokes parameters indirectly, by differencing the brightness temperatures d...

Memory-mapped networks such as Scalable Coherent Interconnect (SCI) [5] and Memory Channel [4] offer a new method for constructing network peripherals by remoting a host’s IO bus. This paper details our experiences from building such an endpoint, and examines how greater support may be provided.

A stimulated Raman scattering microscope with near-infrared picosecond laser pulses at high repetition rates (76MHz) and radio-frequency lock-in detection is accomplished. Based on stimulated Raman loss detection, we demonstrate noninvasive point-by-point vibrational mapping of chemical and biological samples with high sensitivity and without the requirement for labeling of the sample with natu...
