Linearizing response of adaptive interferometer based on dynamic grating in erbium-doped fiber with saturable absorption

Because of the unshifted type of recorded amplitude gratings, adaptive interferometers based on dynamic population gratings in Er-doped fibers with saturable absorption demonstrate an essentially quadratic response and, as a result, are not sensitive enough to detect a small object displacement ( &l...
