ATOMIC OSCILLATOR |
| 摘要 |
An atomic oscillator includes a gas cell having alkali metal atoms sealed therein; alight source that irradiates the gas cell with light; and a light detecting unit that detects the quantity of light transmitted through the gas cell. The light source includes an optical oscillation layer having a first reflective layer, an active layer, and a second reflective layer laminated therein in this order, an electrical field absorption layer having a first semiconductor layer, a quantum well layer, and a second semiconductor layer laminated therein in this order, and a heat diffusion layer that is disposed between the optical oscillation layer and the electrical field absorption layer and has a higher thermal conductivity than that of the second reflective layer. |

1. An atomic oscillator comprising:
a gas cell having alkali metal atoms sealed therein; a light source that irradiates the gas cell with light; and a light detecting unit that detects the quantity of light transmitted through the gas cell, wherein the light source includes an optical oscillation layer having a first reflective layer, an active layer, and a second reflective layer laminated therein in this order, an electrical field absorption layer having a first semiconductor layer, a quantum well layer, and a second semiconductor layer laminated therein in this order, and a heat diffusion layer that is disposed between the optical oscillation layer and the electrical field absorption layer and has a higher thermal conductivity than that of the second reflective layer. |
