Single Photon Detector
Quanfluence’s Single Photon Detector (SPD) is a state-of-the-art device designed for high-sensitivity photon detection, utilizing active quenching. The detector can be configured to work in gated or free running mode.
How It Works
1. Avalanche Biasing: The APD is biased above its breakdown voltage, creating a high electric field within the diode.
2. Photon Detection: When a single photon strikes the diode, it generates an electron-hole pair, triggering an avalanche multiplication of carriers.
3.Signal Readout: The resulting avalanche current produces a measurable pulse, indicating the presence of a photon.
Key Features
- High Sensitivity: Capable of detecting single photons with minimal noise.
- Fast Response Time: Ensures quick recovery for high-speed applications.
- Compact and Robust Design: Ideal for integration into quantum and optical systems.
- Versatility: Supports a wide range of wavelengths, depending on the diode material.
Applications
- Quantum computing and cryptography.
- LIDAR systems.
- Fluorescence and time-resolved spectroscopy.
- Optical communication.
Quanfluence’s SPD combines precision engineering with advanced photonic technologies, making it a reliable choice for cutting-edge research and industrial applications.
