Paper Abstract

Theoretical analysis and experimental investigations are presented on the resolution of a ratiometric wavelength measurement system. Theoretical modelling indicates that the resolution of a ratiometric wavelength measurement system is determined by the signal-to-noise ratio of the input signal and the noise of the photodetectors associated with optical-to-electronic conversion. For the experimental verification, a ratiometric system employing a macrobending standard singlemode fiber is developed and corresponding results are in a good agreement with the theoretical prediction.
