Abstract
Two sub-assemblies in a fiber optic device are fitted to mounting faces of a central section. The mounting faces are typically flat and mutually orthogonal, thus permitting the adjustment of the two sub-assemblies in decoupled degrees of freedom. This results in a simpler adjustment procedure for aligning the two sub-assemblies. Furthermore, the mounting of the sub-assemblies using the orthogonal mounting faces permits the use of relatively thin layers of adhesive that reduce misalignment problems arising from mismatched thermal expansion when the temperature changes.
