Investigations on FM-to-AM modulation compensation using all-fibered wide-range tunable filter

An all-fibered wide-range tunable filter to compensate the frequency modulation to amplitude modulation (FM-to-AM) conversion in laser driver facility is investigated and demonstrated. The filter is based on polarization interference technology and the numerical model referred to Jones matrix method is developed. In the demonstrated compensation experiment, FM-to-AM index α is reduced from 16.78% to 3.12%.
