  • Anodically Bonded Cell, Method for Making Same and Systems Incorporating Same
    Publication number: 20080218281
    Abstract: A cell suitable for use with an atomic clock and a method for making the same, the cell including: a silicon wafer having a recess formed therein; at least one amorphous silicate member having an ion mobility and temperature expansion coefficient approximately that of silicon sealing the recess; and, an alkali metal containing component and buffer gas contained in the recess. The method includes: providing a silicon wafer; forming a cavity through the silicon wafer; introducing an alkali metal containing component and buffer gas into the cavity; and, anodically bonding at least one amorphous silicate member having an ion mobility and temperature expansion coefficient approximately that of silicon to the wafer to close the cavity.
    Type: Application

  • Photonic integrated circuit (PIC) and method for making same
    Patent number: 6788721
    Abstract: A photonic integrated circuit including: at least one photonic component being suitable for operation with a plurality of photons and including an operational material having a bandgap energy close to the energy of the photons; and, at least one photonic component being suitable for operation with the plurality of photons, including an operational material having a bandgap energy substantially higher than the photons and being adjacent to the at least one photonic component including an operational material having a bandgap energy close to the energy of the photons. The at least one photonic component including an operational material having a bandgap energy substantially higher than the photons includes at least one amorphous silicon based alloy material.
