Amplitude and phase modulation of single photons and biphotons
Abstract/Contents
- Abstract
- Single photons and entangled photons are valuable resources in quantum information science. We describe, in this dissertation, the generation of time-frequency entangled pairs of photons with narrow linewidths and coherence times that are about six orders of magnitude longer than those of photons produced via spontaneous parametric downconversion in nonlinear crystals. These photons are produced using the mechanism of electromagnetically induced transparency and the associated slow light effect. Using existing detectors it is possible to temporally resolve the structure of these narrowband photons and commercial electro-optic modulators may be used to manipulate their amplitude and phase. In this context, we discuss three recent experiments. In the first, we demonstrated amplitude modulation, with arbitrary shapes, of heralded single photons. In the second, we demonstrated a Fourier technique to measure the shapes of biphoton wavepackets using fast amplitude modulators and slow detectors. The third experiment is a demonstration of spread spectrum techniques at the single photon level.
