Abstract
In sensor systems that are based on optical fiber Bragg gratings the center wavelength of the grating reflection must be determined with a precision on the order of hundredths of a nm over an operating range of several nm. Systems have been reported using interference filters,1 long-pass transmission filters1 and Mach-Zehnder interferometers2 to provide the required wavelength discrimination. With these there is a trade-off to be made between the conflicting requirements of a large filtering slope (in %/nm) and a wide range of operating wavelengths.
