Physics packages including atomic or molecular vapors and sub-wavelength grating (SWG) waveguides and/or radio frequency (RF) waveguides are provided herein. In some examples, a physics package for interacting with atoms or molecules in a vapor includes a substrate, and a cell sealed to the substrate and storing the vapor. A SWG waveguide may be disposed on the substrate and within the cell. The SWG waveguide may include a plurality of grating segments that are spaced apart from one another and define a gap within the SWG waveguide. The vapor may be located at least within the gap. A first optical coupler couples light into the SWG waveguide such that the light propagates through the vapor located within the gap and interacts with the atoms or molecules in the vapor located within the gap. A second optical coupler receives light from the SWG waveguide.
