Abstract
An atomic oscillator includes: a light-receiving element including a light-receiving section; a cell layer that is laminated on the light-receiving element and includes a cavity having an opening above the light-receiving section; gaseous alkali metal atoms sealed in the cavity; a transparent member to close the opening; and a light-emitting element to emit resonance light to the light-receiving section through the transparent member and the alkali metal atoms.
