“…The cavity is assumed to have a single mode that couples only to the forward propagating fields [31,32]. Details of the device design have been previously reported [30,33]. Using the twodimensional (2D) planar photonic crystal structure, the initial input bichromatic driving field, which includes a cw control field and a cw probe field S in (t) = E c e −iω c t + E p e −iω p t , where ω c and ω p are the carrier frequencies and E c and E p are the amplitudes of the control and probe driving fields, is guided by the waveguide in the crystal plane [14][15][16].…”

We propose a scheme for high-order sideband generation (HSG) by utilizing strong coupling between a single quantum dot (QD) and a photonic crystal cavity beyond the weak-excitation approximation. Here the hybrid system is coherently driven by an external bichromatic field consisting of a continuous-wave (cw) control field and a cw probe field. We take account of nonlinear terms in the Heisenberg-Langevin equations, i.e., the nonlinear nature of the QD, and give an effective method to deal with such a problem. It is shown, due to the presence of nonlinear terms, that the HSG with large intensities can be realized with experimentally achievable system parameters. This investigation may provide further insight into the understanding of solid-state cavity quantum electrodynamics system and find applications in optical comb and communication in a photonic crystal platform. In addition, the present theory can also be applied to other similar systems, such as a single quantum emitter positioned close to a microtoroidal resonator with the whispering-gallery-mode fields propagating inside the resonator.

Single-photon switches and transistors generate strong photon-photon interactions that are essential for quantum circuits and networks. However, the deterministic control of an optical signal with a single photon requires strong interactions with a quantum memory, which has been challenging to achieve in a solid-state platform. We demonstrate a single-photon switch and transistor enabled by a solid-state quantum memory. Our device consists of a semiconductor spin qubit strongly coupled to a nanophotonic cavity. The spin qubit enables a single 63-picosecond gate photon to switch a signal field containing up to an average of 27.7 photons before the internal state of the device resets. Our results show that semiconductor nanophotonic devices can produce strong and controlled photon-photon interactions that could enable high-bandwidth photonic quantum information processing.

“…Point defects can be created by the removal, movement, or size change of one or more holes [52,54] or through a local change in the lattice constant of the periodic array of holes in the PCS [55]. Although considerable work has been done on the coupling of a single point defect to a waveguide [29,53,[56][57][58], many structures of potential interest involve the coupling of several point defects to each other [40][41][42][43][44] or of several point defects to waveguides [26,39,[46][47][48][49]. Examples of two such structures are shown in Fig.…”

We derive a master equation for the total-system density matrix to treat the evolution of quantum dots and photons in a photonic crystal slab with multiple, coupled, lossy defect cavities. In such systems, when the resonant lossy quasimodes of the system overlap in frequency and space, they are generally nonorthogonal. We find that this nonorthogonality can have important consequences for the system evolution. Our formalism allows for the calculation of multiple-photon effects in the presence of quasimode nonorthogonality. It can be applied to the calculation of strong-and weak-coupling dynamics and to first-and second-order photon correlation functions in a wide variety of complicated coupled-cavity systems. As an example, we apply the formalism to an asymmetric two-cavity photonic crystal slab and demonstrate how quasimode nonorthogonality results in oscillations in the decay of the photons out of the system.
