1. A physics package for interacting with atoms or molecules in a vapor, the physics package comprising:
a substrate;
a cell sealed to the substrate and storing the vapor;
a sub-wavelength grating (SWG) waveguide having a length and a width and disposed on the substrate,
the SWG waveguide comprising a plurality of grating segments that are spaced apart from one another and define a gap within the SWG waveguide, the vapor being located at least within the gap;
a first optical coupler configured to couple 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; and
a second optical coupler configured to receive light from the SWG waveguide.
