Absorption Measurements

Predictions of the total band absorption are useful for describing the absorption process in calculations dealing with radiation interaction in absorbing-emitting liquids. Two two-parameter models, similar to the Elsasser and the statistical narrow band models used in gas radiation work, are developed for predicting the total band absorption in regions of the liquid CCl4 spectrum. The parameters, which are considered to be adjustable, can be determined from experimental total band absorption data or, if available, basic spectroscopic information. Results from the models are compared to experimental total band absorption measurements for CCl4 as well as a prediction based on spectral integration.

Entanglement Purification

Abstract Hybrid interfaces between distinct quantum systems play a major role in the implementation of quantum networks. Quantum states have to be stored in memories to synchronize the photon arrival times for entanglement swapping by projective measurements in quantum repeaters or for entanglement purification. Here, we analyze the distortion of a single-photon wave packet propagating through a dispersive and absorptive medium with high spectral resolution. Single photons are generated from a single In(Ga)As quantum dot with its excitonic transition precisely set relative to the Cesium D1 transition. The delay of spectral components of the single-photon wave packet with almost Fourier-limited width is investigated in detail with a 200 MHz narrow-band monolithic Fabry-Pérot resonator. Reflecting the excited state hyperfine structure of Cesium, “slow light” and “fast light” behavior is observed. As a step towards room-temperature alkali vapor memories, quantum dot photons are delayed for 5 ns by strong dispersion between the two 1.17 GHz hyperfine-split excited state transitions. Based on optical pumping on the hyperfine-split ground states, we propose a simple, all-optically controllable delay for synchronization of heralded narrow-band photons in a quantum network.
