Abstract

Understanding the nature of single-photon propagation and any differences to the classical multi-photon regime is essential to better use the escalating number of single-photon technologies. Novel techniques and results are reported that demonstrate a consistent ability to measure the classical group velocity in an optical fiber to an accuracy in the time-of-flight around ±0.2 ns in 30,000 ns. Identical techniques are then applied to single photons to determine their velocity and assess if there is any evidence that Schrödinger frequencies (N+1/2)ω alter the ω-k dispersion diagram. The evidence suggests that photons in a circular fiber show no additional dispersion but travel at the classical group velocity.
