Microcavity controlled coupling of excitonic qubits [PDF]

, 2012
Controlled non-local energy and coherence transfer enables light harvesting in photosynthesis and non-local logical operations in quantum computing. The most relevant mechanism of coherent coupling of distant qubits is coupling via the electromagnetic ...

THEORY OF FWM TRANSMISSION AMPLIFICATION IN PLASMAS

Acta Physica Sinica, 1994
The theory of FWM transmission amplification of ordinary wave mixing in magnetized plasma is investigated. The exact solutions are derived for the degenerate and nondegenerate cases and are adapted for EM wave mixing in unmagnetized plasma.

Tunable coupled-mode dispersion compensation and its application to on-chip resonant four-wave mixing

, 2014
We propose and demonstrate localized mode coupling as a viable dispersion engineering technique for phase-matched resonant four-wave mixing (FWM). We demonstrate a dual-cavity resonant structure that employs coupling-induced frequency splitting at one of

Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking

Laser &Photonics Reviews, EarlyView.
Conventional bandpass filtering strategies may be insufficient for recovering optical waveforms under extremely noisy conditions. We demonstrate a temporal‐cloaking denoising strategy enabled by the temporal Talbot effect, which concentrates the coherent signal of interest into short temporal slots while broadband noise remains temporally spread.

Using tensor properties of four wave mixing in semiconductor optical amplifiers for polarization independent wavelength conversion or pump suppression [PDF]

, 1996
Summary form only given. Wavelength conversion by four-wave mixing (FWM) in semiconductor optical amplifiers (SOAs) has several advantages, including transparency to the modulation format and bit rate.

Broadband Parametric Amplification in AlGaAs‐on‐Insulator Nanowaveguides

Laser &Photonics Reviews, EarlyView.
Harnessing the exceptional nonlinearity of AlGaAs‐on‐insulator nanowaveguides, four‐wave‐mixing parametric amplification achieves a record net on‐chip gain of 56 dB and a gain bandwidth exceeding 415 nm at telecom wavelengths. These results establish AlGaAsOI as a powerful platform for compact, high‐performance integrated nonlinear optical ...
