The Laser Interferometer Gravitational Wave Observatory (LIGO) operates a 40m prototype interferometer on the Caltech campus. The primary mission of the prototype is to serve as an experimental testbed for upgrades to the LIGO interferometers and for gaining experience with advanced interferometric techniques, including detuned resonant sideband extraction (i.e. signal recycling) and dc readout...

Taiji-1 is the first demonstrated experimental satellite of Taiji program in China. Phasemeter one key components laser interferometer which responsible for phase extraction heterodyne signals. In this paper, we present architecture and implementation phasemeter. The DPLL used generally regarded as best choice space missions. We test phasemeter on ground results show that reaches sensitivity 60...
THz oscillators generated via frequency-multiplication of microwaves are facing difficulty in achieving low phase noise. Photonics-based techniques, which optical two tones translated to a wave through opto-electronic conversion, promising if the relative noise between is well suppressed. Here, ($\approx$ 560 GHz) with provided by frequency-stabilized, dissipative Kerr microresonator soliton co...
