1. A photonic crystal device to be used for trapping an atom, the photonic crystal device comprising:
a photonic crystal body;
a slot waveguide; and
an attractive force trap light laser,
wherein the photonic crystal body includes a base and a plurality of lattice elements periodically provided on the base,
wherein the slot waveguide is arranged between a first periodic lattice row and a second periodic lattice row, the slot waveguide including an opening on a first side face of the photonic crystal body,
wherein the attractive force trap light laser is configured to be excited by excitation light incident from the opening, and
wherein the attractive force trap light laser is configured to oscillate at a wavelength longer than a wavelength of an absorption edge of the atom.
