Abstract
We demonstrate the scattering of laser light from two InAs quantum dots coupled to a photonic crystal waveguide, which is achieved by strain-tuning the optical transitions of the dots into mutual resonance. By performing measurements of the intensity and photon statistics of transmitted laser light before and after tuning the dots into resonance, we show that the nonlinearity is enhanced by scattering laser light from two dots. In addition to providing a means of manipulating few-photon optical nonlinearities, our approach establishes opportunities for multiemitter quantum optics in a solid-state platform.
