Abstract

An atomic oscillator includes a gas cell housing alkali metal atoms, a light source providing light to the gas cell, and a light detector that detects an amount of light transmitted through the gas cell. The light source includes a substrate, a first mirror layer on an upper portion of the substrate, an active layer on an upper portion of the first mirror layer, a second mirror layer on an upper portion of the active layer, a first contact layer on an upper portion of the second mirror layer, a light absorption layer on an upper portion of the first contact layer, and a second contact layer on an upper portion of the light absorption layer. As such, an output wavelength and the light output of the light source can be independently adjusted.
