Paper Abstract

A simple modification ofthe typical wide-band monochromator based cut-back system for fiber transmission measurements is presented. To increase the spectral resolution for fiber Bragg gratings measurements the properly blazed monochromator grating was inserted, stepping motor resolution increased and mechanical chopper thoroughly redesigned to avoid signal phase fluctuations. As the result spectral resolution of 0.16nm and signal dynamic range of 30dB was achieved in the 1.5µm region.
