Abstract: The present invention relates to a temperature-compensated optical waveguide device. The temperature-compensated optical waveguide device includes a substrate having a first end and a second end. A first mount is coupled to the first end of the substrate. The first mount includes a first surface, the first surface having a first grove and a first recess intersected by the first groove. A second mount is coupled to the second end of the substrate. The second mount includes a second surface having a second grove and a second recess intersected by the second groove. The first groove and the second groove are substantially aligned with one another; and an optical waveguide fiber coupled to the first mount and the second mount. The optical waveguide fiber has a Bragg grating. The substrate has a first coefficient of thermal expansion, the first mount has a second coefficient of thermal expansion and the second mount has a third coefficient of thermal expansion.

Abstract: One aspect of the present invention is a positioner for an optical element. The positioner includes a base having a receptacle and a substantially planar surface slidably engageable with a substrate. The positioner also includes a mounting platform disposed in the receptacle. The receptacle constrains the mounting platform to translation in a direction substantially perpendicular to the substantially planar surface and the mounting platform is configured so as to be free to rotate about three orthogonal axes within the receptacle. The optical element is coupled to the mounting platform. The optical element is aligned with a second optical element by selectively positioning the mounting platform.

Abstract: The present invention relates to a five-degree of freedom alignment structure 10 for an optical element 28. The alignment structure 10 is a two piece assembly including a submount 12 and a support member 18. An optical element 28 is coupled to the mounting surface 14 of submount 12. The alignment structure 10 is used to align the optical axis 34 of the optical element 28 with the optical axes 32 of another optical element 30.
