Abstract

Two sub-assemblies in a fiber optic device are fitted to respective end faces of a central section, along a longitudinal axis. The end faces of the central section are non-parallel. Butting the sub-assemblies to respective ends of the central section permits relative adjustment of the two sub-assemblies in substantially 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 angled faces permits the use of relatively thin layers of adhesive that reduce misalignment problems arising from mismatched thermal expansion when the temperature changes.
