Abstract: A fiber connector that facilitates alignment of and electrical communication with electrooptical devices on an optical fiber or interposed between optical fibers. An embodiment of in-line optoelectronic device packaging constructed according to principles of the invention includes a ferrule configured to receive an optical fiber with an optoelectronic device mounted on one end of the ferrule, for alignment with the fiber. Electrically-conductive deposits along the side of the ferrule supply electrical energy to or conduct electrical signals from the optoelectronic device. The optoelectronic device-carrying ferrule is inserted in a ceramic sleeve. Another ferrule, maintaining another optical fiber, also is inserted in the ceramic sleeve. Another embodiment constructed according to principles of the invention includes a second optoelectronic device mounted on the second ferrule.

Abstract: Apparatus is disclosed for aligning optical components. The apparatus comprises a light source providing an emission, an optical element for receiving the emission from the light source, and at least one of the light source and the optical element being mounted to a gimbal mount. Adjustment of the light source and/or the optical element mounted to the gimbal mount adjusts the angle of incidence of the emission from the light source on the optical element. This adjustment in turn aligns the optical components. A method is disclosed for aligning optical components. The method comprises generating an emission from a light source, adjusting a gimbal mount on at least one of the light source and an optical element, wherein the angle of incidence of the emission from the light source is adjusted on the optical element, and fixing in place the position of the gimbal mount on the light source and/or the optical element.

Abstract: A method is provided for fabricating microelectromechanically tunable vertical-cavity surface-emitting lasers and microelectromechanically tunable Fabry-Perot filters with precise lateral and vertical dimensional control. Strained reflective dielectric film(s) are applied to a multiple quantum well structure to electronically band-gap-engineer the quantum wells. Appropriate strain in the reflective dielectric film layers is also used to create appropriate curvature in one of the reflective dielectric film stacks so as to form a confocal cavity between a planar reflective dielectric film layer and the curved reflective dielectric film layer in the vertical cavity surface emitting laser or filter.
