Applications
Confocal microscopy: ISM, FLIM, FRET, FCS, STED. The utilization of SPAD arrays increases light collection, enabling innovation in laser-scanning confocal microscopy. This advancement ultimately results in sharper and brighter imaging, offering functional insights into molecular functions, interactions, and environments. SPAD arrays have the following benefits in confocal microscopy:
- Achieve super-resolution using standard confocal microscopes.
- Increase light collection.
- Acceleration of imaging speed.
- Reduction of background noise levels.
Quantum Information: Antibunching, Coincidence Correlation, Quantum Random Number Generation. Temporal photon correlations and photon number resolving (PNR) are pivotal for exploring the quantum properties of light. SPAD arrays, characterized by extremely low crosstalk, facilitate reliable measurements of second and third-order photon correlations, as well as the generation of quantum random numbers for unbreakable encryption. SPAD arrays offer the following advantages in quantum information:
- Simplification of setup with single-chip multi-channel detection.
- Increase data rates with detector parallelization.
- Photon number resolving (PNR) detection.
