Summary
This study shows 1 GHz photon detection with photon number resolution using a multi-pixel photon counter (MPPC) and baseline correction. This high-speed capability is maintained even with multiple photons per pulse.
Area of Science:
- Photonics and Quantum Optics
- High-Speed Detector Technology
Background:
- Accurate photon detection is crucial for quantum information processing and advanced sensing.
- Existing photon detectors often face limitations in speed and photon number resolution at high count rates.
Purpose of the Study:
- To demonstrate photon number resolution at a 1 GHz count rate using a multi-pixel photon counter (MPPC).
- To investigate the performance of a bare MPPC chip on a high-frequency circuit board for enhanced response speed.
Main Methods:
- Utilized a multi-pixel photon counter (MPPC) with a bare chip on a high-frequency circuit board.
- Implemented baseline correction techniques to improve signal accuracy.
- Evaluated photon number resolving capability at repetition rates up to 1 GHz.
Main Results:
- Achieved 1 GHz count rate photon detection with photon number resolution.
- Photon number resolution was maintained at 1 GHz, even with an average of 2.6 photons per pulse.
- Reported photon detection efficiencies of 16% at 450 nm and 4.5% at 775 nm.
- Characterized a dark count rate of 270 kcps and an afterpulse probability of 0.007.
Conclusions:
- The developed MPPC system enables high-speed photon number resolving detection.
- This technology advances capabilities for quantum applications requiring fast and precise photon counting.
