Frequency-chirped readout of spatial-spectral absorption features

Tiejun Chang, R. Mohan, Ming Tian +3 more

This paper examines the physical mechanisms of reading out spatial-spectral absorption features in an inhomogeneously broadened medium using linear frequency-chirped electric fields. A Maxwell-Bloch model using numerical calculation for angled beams with arbitrary phase modulation is used to simulate the chirped field readout process. The simulation results indicate that any spatial-spectral absorption feature can be read out with a chirped field with the appropriate bandwidth, duration, and intensity. Mapping spectral absorption features into temporal intensity modulations depends on the chirp rate of the field. However, when probing a spatial-spectral grating with a chirped field, a beat signal representing the grating period can be created by interfering the emitted photon echo chirped field with a reference chirped field, regardless of the chirp rate. Comparisons are made between collinear and angled readout configurations. Readout signal strength and spurious signal distortions are investigated as functions of the grating strength and the Rabi frequency of the readout pulse. Using a collinear readout geometry, distortions from optical nutation on the transmitted field and higher-order harmonics are observed, both of which are avoided in an angled beam geometry.

Numerical studies of multimodal phase-sensitive parametric amplification

Igor Jovanovic, D. French, Joshua C. Walter +1 more

In the presence of a nonzero idler beam or, equivalently, in the collinear degenerate configuration, optical parametric amplification (OPA) can be phase sensitive. When the photon deamplification mode is selected in the OPA process, amplification of the optical phase occurs instead of the usual amplification of photon number. We demonstrate for the first time, to the best of our knowledge, that the operation of a spatially multimodal optical parametric amplifier in the phase-sensitive mode can result in a significant redistribution of spatial frequencies and near-ideal beam angle amplification. A numerical model is presented for phase-sensitive parametric amplification via three-wave mixing. The model is applied to monochromatic beams and finite beam apertures. The sensitivity of gain to the incident phase, noncollinear angle, and aperture size is studied in particular. Simple conditions are derived for the operation of the optical parametric amplifier in the phase-sensitive mode. Potential applications of the concept are discussed.
