Paper Abstract

A major problem currently affecting the implementation of grating-based optical fiber devices is the drift in wavelength modulation due to the change in the ambient temperature. For accurate and reliable long term operation of these devices, suitable temperature compensation techniques are a necessity. This paper presents a novel temperature compensation technique for in-fiber refractive index grating-based devices and components. The proposed technique is based on the temperature-dependent spectral characteristics of a dielectric multi-layer thin film interference filter fabricated on the endface of refractive-index grating impressed optical fiber. Temperature compensation is achieved by comparing the reflected intensities at the grating- reflected and the interference filter-reflected wavelengths. The proposed scheme also compensates for any light source fluctuations and lead-in fiber bending losses. Thus a self- calibrated optical fiber sensor configuration is obtained.
