We investigated surface plasmon-waveguide hybrid resonances for enhancement of light emission in polymer light-emitting diodes (PLEDs). Hybrid waveguide-plasmon resonances in the visible range for waveguide mode and near IR range for surface plasmons were observed by incorporation of hexagonal Ag dot arrays. Considerable overlap between the emission wavelength of the PLEDs and the waveguide mod...

In recent years, many groups and institutions have been committed to the research of integrated quantum photonic circuit technologies, which key components are waveguide coupled single photon sources. this study, we propose an on-chip waveguide-coupled source that is easily implemented as directly made from dot membrane. order scatter light out plane into detection apparatus, grating output cou...

We derive a general formalism to model the polariton states resulting from the radiation-matter interaction between an arbitrary number of excitonic transitions in semiconductor quantum dots and photon modes in a photonic crystal structure in which the quantum dots are embedded. The Maxwell equations, including the linear nonlocal susceptibility of the exciton transitions in the quantum dots, a...

We describe an approach to optical non-reciprocity that exploits the local helicity of evanescent electric fields in axisymmetric resonators. By interfacing an optical cavity to helicity-sensitive transitions, such as Zeeman levels in a quantum dot, light transmission through a waveguide becomes direction-dependent when the state degeneracy is lifted. Using a linearized quantum master equation,...

Strong interactions between single spins and photons are essential for quantum networks 1 and distributed quantum computation 2. They provide the necessary interface for entanglement distribution 3,4 , non-destructive quantum measurements 5-7 , and strong photon-photon interactions 8-10. Achieving a spin-photon interface in a solid-state device could enable compact chip-integrated quantum circu...

A major challenge in quantum optics and quantum information technology is to enhance the interaction between single photons and single quantum emitters. This requires highly engineered optical cavities that are inherently sensitive to fabrication imperfections. We have demonstrated a fundamentally different approach in which disorder is used as a resource rather than a nuisance. We generated st...

We demonstrate compact optical wavelength conversion architecture for picosecond laser pulses and data streams within photonic band gap waveguides. These multimode waveguides are seeded with resonantly driven, inhomogeneously broadened, distributions of quantum dots whose optical transition center frequency is placed near a sharp discontinuity in the local electromagnetic density of states LDOS...
