Title (EN) PACKAGE FOR CHIP SCALE MAGNETOMETER OR ATOMIC CLOCK
(FR) BOÎTIER POUR HORLOGE ATOMIQUE OU MAGNÉTOMÈTRE À PUCE
Abstract:
(EN) In described examples of a package (200) for a chip scale atomic clock or magnetometer, the package (200) includes a vapor cell using an alkali metal vapor, first and second photodetectors (108 A, 108B), and a laser operable at a frequency that excites an electron transition in the alkali metal vapor. The laser is positioned to provide an optical signal directed through the vapor cell and towards the first photodetector (108A). The package (200) further contains a polarizing beam splitter, which is positioned between the vapor cell and the first photodetector (108 A) to receive the optical signal and to split the optical signal into a first signal (121A) directed toward the first photodetector (108A) and a second signal (121B) directed toward the second photodetector (108B). The first signal (121 A) is orthogonal to the second signal (121B).
(FR) L'invention concerne, selon des exemples décrits, un boîtier (200) pour un magnétomètre ou une horloge atomique à puce, le boîtier (200) comprenant une cellule à vapeur utilisant de la vapeur de métal alcalin, des premier et deuxième photodétecteurs (108A, 108B), et un laser fonctionnant à une fréquence qui excite une transition d'électrons dans la vapeur de métal alcalin. Le laser est positionné pour fournir un signal optique dirigé au travers de la cellule à vapeur et vers le premier photodétecteur (108A). Le boîtier (200) contient en outre un diviseur de faisceau polarisant, qui est positionné entre la cellule à vapeur et le premier photodétecteur (108A) pour recevoir le signal optique et pour diviser le signal optique en un premier signal (121A) dirigé vers le premier photodétecteur (108A) et un deuxième signal (121B) dirigé vers le deuxième photodétecteur (108B). Le premier signal (121A) est orthogonal par rapport au deuxième signal (121B).
