Photon correlation spectroscopy using single-mode optical fibers

Obtaining true beautiful data from any photon correlation experiment demands on, serious attention to improve the signal-to-noise ratio. Single-mode optical fibers provide the ideal receiver optics for photon correlation spectroscopy measurements. The analysis shows that a single-mode fiber can achieve a high collection efficiency and improve the signal-to-noise ratio effectively in photon correlation experiments. All these features are also demonstrated in experiments.
