Area of Science:

Photonics
Integrated Optics
Semiconductor Devices

Background:

Macroscopic modules for single-photon counting and timing are essential but bulky.
Integrating these functionalities onto a single chip offers miniaturization and improved performance.

Purpose of the Study:

To demonstrate a complete single-photon counting and timing module integrated onto a single chip.
To achieve performance comparable to or better than existing macroscopic modules.

Main Methods:

Integration of an active-quenching and active-reset circuit with a single-photon avalanche diode (SPAD) using complementary metal-oxide semiconductor (CMOS) technology.
Characterization of the integrated SPAD's sensitive area, operating overvoltage, photon detection efficiency, dark-counting rate, and dead time.

Main Results:

The integrated SPAD features a 12-microm-diameter sensitive area and adjustable overvoltage up to 20 V.
Photon detection efficiency exceeds 40% around 500 nm at 5-V overvoltage.
Dark-counting rate is below 600 counts/s at room temperature with an overall dead time of 33 ns.

Conclusions:

A fully integrated single-photon counting and timing module on a chip has been successfully demonstrated.
The integrated module offers competitive or superior performance compared to macroscopic counterparts.
This advancement paves the way for compact and high-performance photon detection systems.
