Multi-cavity photonic systems, known as photonic molecules (PMs), are ideal multi-well potential building blocks for advanced quantum and nonlinear optics. A key phenomenon arising in double well potentials is the spontaneous breaking of the inversion symmetry, i.e. a transition from a delocalized to two localized states in the wells, which are mirror images of each other. Although few theoretical...
2D Photonic Crystals (2DPC) allow strong light confinement due to high-Q resonances, which can be realized by point defects (nanocavity) in a periodic array of holes. In III–V semiconductor materials, electronic confinement can also be achieved through the inclusion of nanostructures (i.e. quantum wells). Both electronic and optical confinement leads to the enhancement of light-matter interaction,...
Ultrafast optical switching capabilities of an InP-based photonic crystal cavity are studied using a tapered fiber-assisted coupling scheme. Overall switching times as short as 25 ps were measured with a femtosecond pump and probe technique.
We report on the observation of electromagnetically induced transparency using the hyperfine levels of Er3+:Y2SiO5 crystal and on hole burning spectroscopy in order to identify the Lambda-like three-level system over the inhomogeneously broadened distribution.
