Abstract
Improved ferrule alignment fixtures for use in fiber Fabry-Perot (FFP) filters are provided. The inventive alignment fixtures have ferrule holders with shaped passageways for holding fiber-containing ferrules in three-point contact which allow fiber alignment using a rotary alignment technique. The FFPs have a fiber ferrule assembly which when aligned in the inventive ferrule holder forms an optical cavity between mirrors transverse to the fiber in the ferrule assembly. Wavelength tunable FFPs have a piezoelectric transducer interposed between the ferrule holders which can be used to change the length of the optical cavity and tune the filter.
