In this paper, several Terahertz (THz) high-gain planar integrated antenna arrays developed in University of Electronic Science and Technology of China (UESTC) are introduced based on the diffusion welding technology. Thanks to their wideband, high-gain and compact configuration, these types of antenna arrays present excellent candidates for THz multi-gigahertz capacity wireless systems.
This paper proposes a novel frequency-shifted interferometry (FSI) fiber cavity ring-down (CRD) gas sensing with dual-wavelength differential optical absorption that requires no modulation to a continuous-wave source or without fast detection and switching electronics. The fiber cavity is constructed from standard fiber optical components that include a micro-optical gas cell. FSI-CRD experiments...
We present the quantum noise limited sensitivity curves for the LIGO interferometer incorporating the white light cavity, which shows broadening effect and dips of opto-mechanical resonances for different values of reflectivities of the auxiliary mirror.
