Abstract
Integrated optical devices in which one or more optical fibers are vertically integrated with other optical components in a multilayer arrangement. Optical components include lenses, etalons that may be passive or actuable, WDM filters and beamsplitters, for example. One vertically integrated optical device comprises a fiber socket layer comprising a plurality of sockets including a first socket and second socket arranged proximate to each other, and a lens that has a central axis offset from the cores of the first and second fibers. Optical devices include filters, variable optical attenuators, and switches, for example. A component layer may comprise a spacer layer that provides a predetermined opening that is hermetically sealed to protect sensitive components, such as MEMS devices. Also, a method of forming a socket layer using a two-sided etching process is disclosed. Furthermore, an integrated laser device is disclosed that includes a laser layer.
