Atomic spectroscopy with air-slot photonic crystals [1] is important for future quantum information devices. Until now, we demonstrated air-bridge SiN photonic crystal [2] but have not implemented input and output waveguides. In this study, we will investigate SiN based slot photonic crystal waveguide with input and output waveguides and will also report primitive result about atomic spectroscopy with the SiN photonic crystals and rubidium atoms.
