ABSTRACT:
A single wafered optical fiber ferrule assembly useful in fixed and tunable fiber Fabry-Perot (FFP) filters is described. The ferrule assembly contains a wafered ferrule with embedded mirror and a mirrored-end ferrule which are aligned with respect to each other along a longitudinal axis in an alignment fixture. The ferrules are aligned and spaced with respect to each other to maximize transmission of light of a selected wavelength through the filter. The wafered ferrule is composed of a fiber ferrule and a wafer greater than or equal to about 5 .mu.m in thickness which are bonded together with a mirror embedded between the wafer and the ferrule. The ferrule assembly forms a FP optical resonance cavity between the two mirrors. The single wafered ferrule design produces more easily manufactured and more stable FFP than prior art designs.
