Design of a Phase Sensor Applied in the Optical Phase-Locked Loop Based on a High-Speed Coherent Laser Communication System

IEEE Access, 2018
The background of our research is, designing a precise phase detection sensor for high-speed coherent homodyne systems, and combining it with optical phase-locked loops (OPLLs) to achieve coherent demodulation and carrier recovery.

Lasing from single, stationary, dye-doped glycerol/water microdroplets located on a superhydrophobic surface

, 2007
We report laser emission from single, stationary, Rhodamine B-doped glycerol/water microdroplets located on a superhydrophobic surface. In the experiments, a pulsed, frequency-doubled Nd:YAG laser operating at 532 nm was used as the excitation source ...

Overview of one-point-to-multi-point space laser communication technology

Tongxin xuebao
Laser communication serves as a key enabler for the future space information infrastructure. Since traditional point-to-point mode suffers from low resource utilization, complex structure, and limited scalability, the one-point-to-multi-point ...

Optical superheterodyne receiver uses laser for local oscillator [PDF]

, 1966
Optical superheterodyne receiver uses a laser coupled to a frequency translator to supply both the incident signal and local oscillator signal and thus permit reception of amplitude modulated video bandwidth signals through the atmosphere.

Suppression of ac Stark shift scattering rate due to non-Markovian behavior

, 2015
The ac Stark shift in the presence of spontaneous decay is typically considered to induce an effective dephasing with a scattering rate equal to $ \Gamma_s |\Omega|^2/\Delta^2 $, where $ \Gamma_s $ is the spontaneous decay rate, $ \Omega $ is the laser ...
