By using a feedback-stabilized fiber Mach-Zehnder interferometer (MZI) with a PZT-based phase shifter, a novel method for measurement of laser coherence length is demonstrated based on pulses interference. Experimental results show that the......

Based on elasto-optic effect theory, we present a simplified model for the fiber squeezer assisted with a piezoceramic actuator (PZT), and it is experimentally demonstrated with reasonable approximation. Results show that there is a quadrat......

We demonstrate an ultralow-noise single-photon detection system based on a sensitive photomultiplier tube (PMT) with precise temperature control, which can capture fast single photons with intervals around 10 ns. By improvement of the elect......
