“…Quantum interference in polarization-sensitive measurements of intensity and photon correlations have been studied in the past, especially in the context of two four-level atoms [42][43][44][45][46]. More recently, an interesting experiment by Chen et al [47] showed that the excitation spectra of an artificial atom with orthogonal dipoles exhibits unconventional line shapes due to polarization-dependent interference. Motivated by this, here, we theoretically investigate the resonance fluorescence from a driven V-system with orthogonal dipoles.…”

We present a scheme that enables the observation of interference effects in the resonance fluorescence of a V-type atom with orthogonal dipole moments. Specifically, we consider the atomic configuration of a J g = 0 to J e = 1 transition driven by a single laser field. By employing polarization-sensitive detection in such a way that the light emitted on the two transitions become indistinguishable, we show that one can simulate the effect of vacuum-induced coherence on the resonance fluorescence of this system. In addition, we demonstrate the possibility of realizing atomic transitions with both parallel and antiparallel dipole moments and their effects on the fluorescence spectrum. The interference induced leads to interesting features in the fluorescence spectrum such as asymmetric spectral peaks, enhancement and suppression of the sidebands, and disappearance of fluorescence in the particular direction of detection. The numerical results are understood in the context of the dressed states of the combined atom–field system.

Изучено влияние двухфотонных процессов на поглощение в системе экситонов и биэкситонов при двухимпульсном взаимодействии. Показано, что учет двухфотонных процессов приводит к возможности наблюдения несимметричного эффекта Аутлера--Таунса. При определенных величинах падающих полей возможно исчезновение эффекта Аутлера--Таунса, связанное с квантовой интерференцией всех механизмов взаимодействия. Предсказана возможность управления спектром поглощения с помощью изменения интенсивностей полей и расстроек резонанса падающего излучения. Ключевые слова: экситоны, биэкситоны, расщепление Аутлера--Таунса.

“…Resonant excitation of a single quantum emitter combined with fluorescence detection was a long-term experimental challenge mainly due to the inability to spectrally discriminate the weak fluorescence from the strong excitation scattering. This difficulty, however, has been successfully overcome in the past decade by two different approaches: dark-field confocal excitation based on polarization discrimination 1,2,3,4,5 , and orthogonal excitation-detection based on spatial mode discrimination 6,7,8,9,10,11,12,13,14 . Both approaches demonstrate a strong capability to significantly suppress laser scattering and thus are widely adopted in various experiments, for example, observation of spin-photon entanglement 5,15,16 , demonstration of dressed states 2,7,12,17,18,19,20,21,22,23,24,25,26 , and coherent manipulation of confined spins 3,27,28,29,30 .…”

The ability to perform simultaneous resonant excitation and fluorescence detection is important for quantum optical measurements of quantum dots (QDs). Resonant excitation without fluorescence detection - for example, a differential transmission measurement - can determine some properties of the emitting system, but does not allow applications or measurements based on the emitted photons. For example, the measurement of photon correlations, observation of the Mollow triplet, and realization of single photon sources all require collection of the fluorescence. Incoherent excitation with fluorescence detection - for example, above band-gap excitation - can be used to create single photon sources, but the disturbance of the environment due to the excitation reduces the indistinguishability of the photons. Single photon sources based on QDs will have to be resonantly excited to have high photon indistinguishability, and simultaneous collection of the photons will be necessary to make use of them. We demonstrate a method to resonantly excite a single QD embedded in a planar cavity by coupling the excitation beam into this cavity from the cleaved face of the sample while collecting the fluorescence along the sample's surface normal direction. By carefully matching the excitation beam to the waveguide mode of the cavity, the excitation light can couple into the cavity and interact with the QD. The scattered photons can couple to the Fabry-Perot mode of the cavity and escape in the surface normal direction. This method allows complete freedom in the detection polarization, but the excitation polarization is restricted by the propagation direction of the excitation beam. The fluorescence from the wetting layer provides a guide to align the collection path with respect to the excitation beam. The orthogonality of the excitation and detection modes enables resonant excitation of a single QD with negligible laser scattering background.
