Abstract

A photonic crystal device to be used for trapping an atom and including a photonic crystal body, a slot waveguide, and an attractive force trap light laser. The photonic crystal body includes a base and a plurality of lattice elements periodically provided on the base, the slot waveguide is arranged between periodic lattice rows and includes an opening on one side face of the photonic crystal body, and the attractive force trap light laser is excited by excitation light incident from the opening and oscillates at a wavelength being longer than a wavelength of an absorption edge of the atom.
