The coupling of single photons and single atoms establishes the most fundamental building block of quantum optics. In the solid state some organic dye molecules and rare earth ions have been shown to possess a remarkable photostability and Fourier-limited transitions at cryogenic temperatures. In this talk, we present an overview of our activities in solid state quantum optics. In the first part, we discuss the coupling of single molecules to photons confined in a subwavelength waveguide. Extinction, fluorescence excitation, and resonance fluorescence spectroscopy provide us with high spatial and spectral information on a large number of molecules in the waveguide. Our platform is ideally suited to study the coherent coupling of two or more emitters within a single optical mode. In the second part, we report on the spectroscopy and microscopy of single rare earth ions in a crystalline host. These quantum objects offer an atomic energy level scheme with a plethora of narrow optical transitions and quantum states with extremely long coherence times. Furthermore, the crystalline nature of the host material lends itself to on-chip integration. We discuss our efforts for increasing the emission of single ions via coupling to microcavities and our plans for the realization of quantum photonic circuits using waveguides.
