Coherent analysis of quantum optical sideband modes.

چکیده
We demonstrate a device that allows for the coherent analysis of a pair of optical frequency sidebands in an arbitrary basis. We show that our device is quantum noise limited, and hence applications for this scheme may be found in discrete and continuous variable optical quantum information experiments.

Engineering the electromagnetic vacuum for controlling light with light in a photonic-band-gap microchip
We demonstrate a trimodal waveguide architecture in a three-dimensional (3D) photonic-band-gap (PBG) material, in which the local electromagnetic density of states (LDOS) within and adjacent to the waveguide exhibits a forklike wavelength filter characteristic. This facilitates the control and switching of one laser beam with other laser beams ( ,1 mW steady-state holding power and ,5 nW switch...
متن کاملTerahertz Sideband Generation and Coherent Control in Semiconductor Microcavities
The controlled variation of the temperature, magnetic field, electrical bias, and quantum-well (QW) thickness [1] have all been employed to afford tunability of the exciton–cavity-photon coupling in semiconductor microcavities (MC’s). Time-dependent knobs, however, have attracted scant attention. As we show in this Letter, the modulation of the optical properties of a MC at THz frequencies may ...
متن کاملSimultaneous cooling of axial vibrational modes in a linear ion-trap
In order to use a collection of trapped ions for experiments where a well defined preparation of vibrational states is necessary, all vibrational modes have to be cooled to ensure precise and repeatable manipulation of the ions’ quantum states. A method for simultaneous sideband cooling of all axial vibrational modes is proposed. By application of a magnetic field gradient the absorption spectr...
متن کاملModel of the optical emission of a driven semiconductor quantum dot: phonon-enhanced coherent scattering and off-resonant sideband narrowing.
We study the crucial role played by the solid-state environment in determining the photon emission characteristics of a driven quantum dot. For resonant driving, we predict a phonon enhancement of the coherently emitted radiation field with increasing driving strength, in stark contrast to the conventional expectation of a rapidly decreasing fraction of coherent emission with stronger driving. ...
متن کاملOptical sideband generation up to room temperature with mid-infrared quantum cascade lasers.
Mid-infrared (MIR) sideband generation on a near infrared (NIR) optical carrier is demonstrated within a quantum cascade laser (QCL). By employing an externally injected NIR beam, E(NIR), that is resonant with the interband transitions of the quantum wells in the QCL, the nonlinear susceptibility is enhanced, leading to both frequency mixing and sideband generation. A GaAs-based MIR QCL (E(QCL)...
