Abstract
An optical waveguide is provided comprising a non-solid core layer surrounded by a solid-state material, wherein light can be transmitted with low loss through the non-solid core layer. A vapor reservoir is in communication with the optical waveguide. One implementation of the invention employs a monolithically integrated vapor cell, e.g., an alkali vapor cell, using anti-resonant reflecting optical waveguides, or ARROW waveguides, on a substrate.
Claims1
A method for sealing a vapor source to an integrated waveguide chip, wherein the vapor source comprises a metal cylinder, the method comprising:
- attaching a first end of the metal cylinder to the chip using at least one member of a group consisting of glue, epoxy, and solder;
- placing an amount of alkali metal inside the metal cylinder;
- establishing a vacuum environment within the metal cylinder;
- and
- crimp sealing a second end of the metal cylinder.
