Development and Characterization of a Fiber Optic Thermal Insulator (FOTI)

Abstract

To reduce the effect that transient temperature fluctuations had on gratings, utilization of passive temperature control via insulation was investigated. For this, a novel packaging technique involving evacuated capsules was developed. In addition to determining the required vacuum pressure needed to insulate the gratings, numerous devices were fabricated and their performance was measured. In one design, the insulator showed a 30 dB improvement in limiting temperature fluctuations and a time constant 5000 times greater than bare fiber.
