Abstract: Vapor cells may include a body including a cavity within the body. A first substrate bonded to a second substrate at an interface within the body, at least one of the first substrate, the second substrate, or an interfacial material between the first and second substrates may define at least one recess or pore in a surface. A smallest dimension of the at least one recess or pore may be about 500 microns or less, as measured in a direction parallel to at least one surface of the first substrate partially defining the cavity.

Abstract: Methods of using vapor cells may involve providing a vapor cell including a body defining a cavity within the body. At least a portion of at least one surface of the vapor cell within the cavity may include at least one pore having an average dimension of about 500 microns or less, as measured in a direction parallel to the at least one surface. A vapor pressure of a subject material within the cavity may be controlled utilizing the at least one pore by inducing an exposed surface of a subject material in a liquid state within the at least one pore to have a shape different than a shape the exposed surface of the subject material in a liquid state would have on a flat, nonporous surface.

Abstract: A method of manufacturing a vapor cell includes forming a body of the vapor cell having walls defining a cavity thereinbetween, the cavity having an amount of a subject material contained therein. The method also includes forming a pore structure having a substrate material with pores of a substantially uniform dimension formed therein, the pore structure disposed along a portion of one or more of the walls of the vapor cell. The method further includes forming a liner material of a uniform thickness over one or more internal surfaces of the pores, wherein the subject material exhibits a reduced wetting angle on the liner material which is less than a wetting angle of the subject material on the substrate material.
