Abstract
A temperature-compensating package for an optical feature such as a fiber grating, a fiber arrangement suitable for use in such a temperature compensating arrangement, methods of manufacture for such packages and arrangements, and methods of temperature compensating an optical feature such as a fiber grating are provided. A precise temperature compensating arrangement can be provided by adjusting the length of two sections of material for any fiber. The arrangement has a first material having a positive coefficient of thermal expansion and a second portion made of a second material having a negative coefficient of thermal expansion, the first and second portions being arranged to form an end-to-end arrangement such that a selected combined coefficient of thermal expansion for the fiber holder results.
