Abstract
This work is concerned with the applications of Bragg-grating fiber-optic filters. First, on the basis of recently pointed out discrepancies between different formulations of the coupled-mode theory, we revisit the design process of devices intended for amplified spontaneous emission noise filtering in DWDM systems. Next, the use of these same basic filter structures in temperature sensing is discussed. The proposed device employs a dual-wavelength measurement scheme of the optical power being transmitted by the Bragg filter, thereby tracking temperature variations while simultaneously canceling spurious readings due to random optical power fluctuations.
