Title: Fiber fabry-perot etalon
Inventor: STONE JULIAN
IPC: G02B26/00
Filed: 1987-03-04
Granted: 1991-01-08
Abstract: FIBER FABRY-PEROT ETALON     Abstract A practical, manufacturable Fabry-Perot etalon and method for fabricating the same is disclosed.  The plastic coating material is removed from the ends of a predetermined length of single mode fiber.  A small area of the glass fiber is exposed by scraping away the coating near the center of the fiber on one side, and the fiber is then broken at this point forming a small gap.  The remaining coating holds the broken fiber together and automatically matches the pieces in alignment.  Mirrors of desired reflectivity are applied to the polished fiber ends, either by gluing on discrete mirrors or by applying multilayer dielectric coatings.       The fiber/mirror structure is mounted onto a piezoelectric substrate.  A voltage is applied to the piezoelectric substrate, causing longitudinal expansion of the fiber gap and providing the scanning means to obtain a spectrum of resonant wavelengths.
