ABSTRACT:
This invention relates to temperature compensated FFPs with improved means for alignment of optical fibers. The invention provides ferrule holders with shaped ferrule passageways, as components of FFP alignment fixtures, in which optical fiber ends can be readily aligned using the ferrule rotary alignment method. The ferrule holders have a composite structure facilitating temperature compensation required for applications to PZT-tuned FFPs. The ferrule holder has a core and peripheral region made of materials having different thermal expansion coefficients. The holder core in contact with the ferrule is made of a material having a thermal expansion coefficient substantially matched to that of the ferrule material. In addition, ferrule holders are provided with a means for changing the points of contact between a secured ferrule and its holder which allows wavelength drift as a function of temperature in FFPs to be adjusted.
