Schematic illustration of photon scattering from a two-level emitter in a photonic crystal waveguide (PhC WG). A weak coherent state is coupled to the PhC WG via a shallowly etched grating (SEG). In the photon scattering image, a single-photon wave packet is mainly reflected by elastic scattering on a two-level emitter, while the two-photon wave … Read more
