1. A vapor cell, comprising:
a body defining a cavity within the body, the body comprising a first substrate bonded to a second substrate at an interface, a first window located on a side of the first substrate opposite the second substrate, and a second window located on a side of the second substrate opposite the first substrate;
the first substrate comprising a first porous volume extending around a circumference of the cavity and located proximate to the first window; and
the second substrate comprising a second porous volume extending around the circumference of the cavity and located proximate to the second window.
