Using a simple and cost-effective water jet process, silicon etch depth limitations are
overcome to realize a 6 mm deep atomic vapor cell. While the minimum silicon feature size …

Light shifts are known to be an important limitation to the mid-and long-term fractional
frequency stability of different types of atomic clocks. In this article, we demonstrate the …

The mid-term fractional frequency stability of miniaturized atomic clocks can be limited by
light-shift effects. In this Letter, we demonstrate the implementation of a symmetric auto …

We propose a model to reduce the influence that the light-shift induced frequency drift has
