ABSTRACT
A crossed resonator Fabry-Perot device is analyzed for a collection of nonlinear-optical materials, including bulk semiconductors, the intraband transition in a multiple quantum well, organic polymers, and semiconductor-doped glasses, to determine its suitability for photonic switching and optical computing. We find that as an optical switch the crossed resonator offers a considerably steeper threshold and somewhat flatter wings than a single Fabry-Perot resonator and that to achieve optical gain the absorption per pass must be lower than 0.05.
ABSTRACT
Using our quantum theory of multiwave mixing, we derive formulas for the intracavity squeezed variances generated by nondegenerate four-wave mixing in a cavity and illustrate the results with variance spectra as functions of side-mode/pump beat frequency.
ABSTRACT
We present calculations of the spontaneous-emission spectrum from a two-photon two-level system in the presence of an arbitrarily intense monochromatic field at half of the two-photon transition frequency. The single-photon counterpart to this is called resonance fluorescence. Because of the complexity of the two-photon two-level model, many effects arise that are absent in the one-photon problem. In particular, we show how the Rayleigh scattering from this system is markedly different and discuss the role of Stark shifts on the emission spectrum.
