Abstract
A physical system for a chip-scale coherent population trapping (CPT) atomic clock. The physical system includes: a vertical-cavity surface-emitting laser (VCSEL) device, a first polarizing beam splitter, a first λ/4 wave plate, a chip of an atomic vapor cell, a second λ/4 wave plate, a reflection device, a lens, a second polarizing beam splitter, and a photo detector. The first polarizing beam splitter, the first λ/4 wave plate, the chip of the atomic vapor cell, the second λ/4 wave plate, and the reflection device are disposed in sequence. The lens, the second polarizing beam splitter, and the photo detector are disposed in sequence.
