InGaAs/InP single-photon avalanche diode (SPAD) with small active diameter and backside microlens was fabricated and its dark count and after-pulse noises were characterized. In addition, by optimizing multiplication layer and reducing the active dia

The after-pulsing effect is a common problem in high-speed and low-noise single-photon detection based on single-photon avalanche diodes (SPADs). This article presents a dual anode InGaAs/InP SPAD (DA-SPAD) with two separate anode output ports that c

The practical realization of long-distance entanglement-based quantum communication systems strongly rely on the observation of highly stable quantum interference between correlated single photons. This task must accompany active stabilization of the

We present a low jitter frequency up-conversion detector based on quasi-phase matched sum frequency generation in a periodically poled LiNbO3 waveguide for efficient single-photon detection at 1.5 μm telecommunication wavelengths. The maximum detect

This paper presents a pulse base effect on the Brillouin gain spectrum that can be obtained by Brillouin optical time-domain analysis (BOTDA), which uses a pump–probe system. For theoretical analysis of the pulse base effect, we propose a theoretic

Brillouin scattering-based fiber optic sensors are useful to measure strain or temperature in a distributed manner. Since the Brillouin frequency of an optical fiber depends on both the strain and temperature, it is very important to know whether the

We report on single-photon interference experiments in a Michelson-type interferometer built with two 6-km-long fiber spools, as well as on the active stabilization of the interferometer. A weak coherent light signal was (de-) multiplexed with a stro
