Paper Abstract

In paper methodological aspects of symmetric double frequency reflectometry system for fiber Bragg structure control are discussed. Amplitude phase conversion method for forming double frequency oscillations from harmonic signals is proposed. This method is based on the fact that phase modulation with certain indexes could decrease an amplitude of initial frequency and produce two symmetric side lobes. Basics of amplitude phase conversion of coherent single frequency radiation to double frequency and its distinguished features of frequency-shifted spectral components symmetrical position relatively suppressed frequency of initial radiation, high level of spectral purity, stable output radiation, and high conversion ratio are illustrated. Information structure of symmetric double frequency signal is also considered.
