“…Fast switching rates are currently under demand by both optical information technologies [1][2][3][4][5][6][7][8][9] and by fundamental studies that aim to manipulate light-matter interactions at femtosecond time scales [10][11][12][13]. The electronic Kerr effect inherently provides the highest possible speed given its virtually instantaneous response nature [7,[14][15][16][17][18][19][20].…”

We have switched GaAs/AlAs and AlGaAs/AlAs planar microcavities that operate in the "Original" (O) telecom band by exploiting the instantaneous electronic Kerr effect. We observe that the resonance frequency reversibly shifts within one picosecond when the nanostructure is pumped with low-energy photons. We investigate experimentally and theoretically the role of several parameters: the material backbone and its electronic bandgap, the quality factor, and the duration of the switch pulse. The magnitude of the frequency shift is reduced when the backbone of the central λ-layer has a greater electronic bandgap compared to the cavity resonance frequency and the frequency of the pump. This observation is caused by the fact that pumping with photon energies near the bandgap resonantly enhances the switched magnitude. We thus find that cavities operating in the telecom O-band are more amenable to ultrafast Kerr switching than those operating at lower frequencies, such as the C-band. Our results indicate that the large bandgap of AlGaAs/AlAs cavity allows to tune both the pump and the probe to the telecom range to perform Kerr switching without detrimental two-photon absorption. We observe that the magnitude of the resonance frequency shift decreases with increasing quality factor of the cavity. Our model shows that the magnitude of the resonance frequency shift depends on the pump pulse duration and is maximized when the duration matches the cavity storage time to within a factor two. In our experiments, we obtain a maximum shift of the cavity resonance relative to the cavity linewidth of 20%. We project that the shift of the cavity resonance can be increased twofold with a pump pulse duration that better matches the cavity storage time. We provide the essential parameter settings for different materials so that the frequency shift of the cavity resonance can be maximized using the electronic Kerr effect.

“…While two coupled cavities, by means of Purcell effect, can realize a bright source of entangled photon pairs as well as an ultra-fast control of the emission rate of embedded quantum emitters [7][8]. In addition, the significant system of three coupled cavities has led to the proposal of an optical analogue of the Josephson interferometer and has been recently proposed for mode tailoring in quantum electrodynamics experiments [9][10]. Strongly interacting resonators would represent the basis for developing two-qubit gates in integrated structures [11].…”

Arrays of photonic cavities are relevant structures for developing large-scale photonic integrated circuits and for investigating basic quantum electrodynamics phenomena, due to the photon hopping between interacting nanoresonators. Here, we investigate, by means of scanning near-field spectroscopy, numerical calculations and an analytical model, the role of different neighboring interactions that give rise to delocalized supermodes in different photonic crystal array configurations.The systems under investigation consist of three nominally identical two-dimensional photonic crystal nanocavities on membrane aligned along the two symmetry axes of the triangular photonic crystal lattice. We find that the nearest and next-nearest-neighbour coupling terms can be of the same relevance. In this case, a non-intuitive picture describes the resonant modes, and the photon hopping between adjacent nanoresonators is strongly affected. Our findings prove that exotic configurations and even post-fabrication engineering of coupled nanoresonators could directly tailor the mode spatial distribution and the group velocity in coupled resonator optical waveguides.

“…11 An approach to overcome these limitations, recently proposed in Ref. 20, relies on an array of three coupled cavities, where an antisymmetric detuning of the outer cavities produces a large change in the field of the supermode inside the third (target) resonator without changing its frequency. [21][22][23] Such a system allows the control of the single-photon temporal waveform and the Rabi oscillations in real time, with a modulation speed that solely depends on the detuning technique.…”

“…[21][22][23] Such a system allows the control of the single-photon temporal waveform and the Rabi oscillations in real time, with a modulation speed that solely depends on the detuning technique. 20 Here, we experimentally implement this concept and demonstrate the full control of the SE of an ensemble of semiconductor quantum dots (QDs) integrated within three coupled cavities. By exploiting the supermodes of the system, we are able to deterministically tailor the mode field experienced by the emitters inside a target cavity, modulating the SE rate from the uncoupled limit to full inhibition.…”

Quantum dots (QDs) interacting with confined light fields in photonic crystal cavities represent a scalable light source for the generation of single photons and laser radiation in the solid-state platform. The complete control of light-matter interaction in these sources is needed to fully exploit their potential, but it has been challenging due to the small length scales involved. In this work, we experimentally demonstrate the control of the radiative interaction between InAs QDs and one mode of three coupled nanocavities. By non-locally moulding the mode field experienced by the QDs inside one of the cavities, we are able to deterministically tune, and even inhibit, the spontaneous emission into the mode. The presented method will enable the real-time switching of Rabi oscillations, the shaping of the temporal waveform of single photons, and the implementation of unexplored nanolaser modulation schemes.
