Certain preferred embodiments of the stacked, optically coupled etalon wafers disclosed here comprise first and second Fabry-Perot thin film coatings on parallel opposite sides of a cavity formed by a bulk optic wafer comprising a solid, optically transparent body and a wedge coating on a surface of the optically transparent body. The wedge coating underlies the first Fabry-Perot coating and the axial dimension of the bulk optic wafer, i.e., the dimension of the bulk optic wafer (with the wedge coating and any thickness-adjustment layer) in the direction of light passage, defines the cavity spacing of an etalon wafer. As used here, in certain instances as will be clear from context, the term “bulk optic wafer” refers to a component of the etalon wafers disclosed above comprising a solid, optically transparent body, such as an optically transparent substrate wafer, together with the wedge coating and/or a thickness-adjustment layer. The solid, optically transparent body is an optically transparent substrate having first and second generally flat surfaces on opposite sides, which is self-supporting in the sense that it does not require an underlying support member to retain its shape and integrity during handling, packaging and transport in manners typical for optical elements intended for use as sensors, fiber optic communication system components or the like. Most preferably the transparent body of the bulk optic wafer is a monolithic body, that is, a one-piece, unitary, self-supporting body of material. The wedge coating overlies a surface of the transparent body of the bulk optic wafer, and there may or may not be a visible or discernable seam or interface between them. In certain preferred embodiments the wedge coating and optional thickness adjustment layer are formed of material that is the same as that of the optically transparent body. In other preferred embodiments, the wedge coating and/or thickness-adjustment layer are formed of a material comprising substantially the same refractive index as the material comprising the optically transparent body, e.g. the refractive indices differ by less than about �0.01. It may, therefore, be difficult or impossible to see the boundaries between the bulk optic wafer, the wedge-correction layer and the thickness-adjustment layer. It is, of course, desirable generally that there be no or substantially no optical effect at such boundaries which would adversely impact the performance of the etalon wafer or the stacked and optically coupled etalon wafers. Thus, the wedge coating and thickness-adjustment coating may be difficult or even impossible to distinguish from the material of the underlying optically transparent body, at least without observing the manner in which the etalon wafer was produced. This typically will not be the case where different materials are used for the optically transparent body, wedge coating and thickness-adjustment coating. In any event, these components of the bulk optic wafer are distinct from each other in the function they perform and in their position in the bulk optic wafer.
