PASSIVE TEMPERATURE-COMPENSATING PACKAGE FOR FIBER BRAGG GRATING DEVICES

摘要

A passive temperature compensating package for a fiber Bragg grating device (300) in which the fiber Bragg grating is written to the fiber prior to the temperature compensation members (304) and (306) are being set. As the temperature of the package increases the fiber is de-stressed and at the desired proper resonant frequency, the fiber containing the fiber Bragg grating (300) is secured to the package. As the package cools and expands, the fiber is pre-stressed and maintains the desired resonant frequency.
