Temperature compensated ferrule holder for a fiber Fabry-Perot filter

摘要: The invention relates generally to optical interference filters and interferometers. Methods, devices device components for fiber Fabry - Perot (FFP) ferrule holders (100) are provided. provides FFP capable of good radial longitudinal alignment. An exemplary holder the present is substantially constraining motion a pair ferrules (155,160) in all directions except direction parallel axis, thereby allowing resonance cavity filter be adjusted while maintaining further temperature compensated that stable with respect wavelength drift over useful range operating conditions. In addition, which particularly monitoring ambient conditions measuring physical properties mechanical phenomena.
