Research Abstract

The purpose of this research project is to develop a high-performance tunable optical filters suitable for wavelength division multiplexing by using high-precision LiNbO_3 piezoelectric actuators. The results obtained in this project are as follows :
(1) A Fabry-Perot tunable optical filter built in a pair of optical-fiber connector ferrules has been designed and fabricated. Dielectric mirrors of high reflectivity are formed on a polished end of fibers to form a Fabry-Perot etalon, and the cavity length is varied by two piezoelectric actuators made of 140゚ rotated Y-cut LiNbO_3 single crystals. A tunable optical filter having a free spectral range of 14nm, a finesse of 140, and a FWHM of 0.1nm has been obtained. However, a small amount of hysteresis is observed that might be caused by friction between the ferrules and a metallic sleeve.
(2) Another type of Fabry-Perot tunable filter that employs a pair of quartz plates with dielectric mirrors as an etalon is presented. The mirrors are placed in a path of a collimated optical beam, and the etalon spacing is controlled by a bending or a stretching actuator made of 140゚ rotated Y-cut LiNbO_3 single crystals. These filters work well, but further investigation is required to improve the filter performance.
