    Abstract: MEMS-actuated optical switches can be implemented on photonic chips. These switches are compact, essentially planar, simple to implement and include only one moving MEMS component per switch. The switches exhibit low optical loss, require low power to operate, and are simple to control and easy to integrate with other optical devices. Each switch has two optical waveguides that are optically coupled in an ON switch state and not coupled in an OFF switch state. An end or a medial section of one of the two waveguides may translate between the ON and OFF states to affect the coupling. Alternatively, a coupling frustrator may translate between the ON and OFF states to affect the coupling.

    Abstract: A bi-directional device for generating or absorbing atoms or ions. In some embodiments, the device comprises a solid-phase ion-conducting material, a first electrode positioned on a first surface of the solid-phase ion-conducting material, and a second electrode positioned on a second surface of the solid-phase ion-conducting material. The first electrode includes a plurality of triple phase boundaries, each located at an interface between the solid-phase ion-conducting material and the first electrode. A density of the triple phase boundaries is in the range of about 104 m/m2 to about 2×107 m/m2 on the first surface of the ion-conducting material. A method of operating the bi-directional device and a method of fabricating a bi-directional device are also provided.
