Quantum state-controlled directional spontaneous emission of photons into a nanophotonic waveguide
The spin of light in subwavelength-diameter waveguides can be orthogonal to the propagation direction of the photons because of the strong transverse confinement. This transverse spin changes sign when the direction of propagation is reversed. Using this effect, we demonstrate the directional spontaneous emission of photons by laser-trapped caesium atoms into an optical nanofibre and control th...
متن کاملUltra-compact broadband higher order-mode pass filter fabricated in a silicon waveguide for multimode photonics.
An ultra-compact and broadband higher order-mode pass filter in a 1D photonic crystal silicon waveguide is proposed and experimentally demonstrated. The photonic crystal is designed for the lower order mode to work in the photonic band gap, while the higher order mode is located in the air band. Consequently, light on the lower order mode is prohibited to pass through the filter, while light on...
متن کاملEfficient coupling between a photonic crystal nanocavity and a waveguide with directional end-facet emission
Monolithic integration of photonic crystal lasers and waveguides is proposed using quantum well intermixing. Coupling between a double-heterostructure nanocavity and a regular single-line-defect waveguide is optimized to have a high coupling efficiency (93%) and a high quality factor (6.8× 103) without fine-tuning of the lattice. The design is completed with a waveguide exit of robust direction...
متن کاملMultimode waveguide speckle patterns for compressive sensing.
Compressive sensing (CS) of sparse gigahertz-band RF signals using microwave photonics may achieve better performances with smaller size, weight, and power than electronic CS or conventional Nyquist rate sampling. The critical element in a CS system is the device that produces the CS measurement matrix (MM). We show that passive speckle patterns in multimode waveguides potentially provide excel...
