Abstract
Theoretical and experimental results of three different high-birefringent fiber
loop mirrors with output ports are analyzed. For theoretical model, the Jones matrix
analysis is used. The theoretical studies present similar results for all experimental
configurations. The last configuration is tested as an interrogation system where the
spectral response arises from the combination of the reference signal modulated by the
sensor signal. The configuration is characterized in strain with the phase changes
recovered from two quadrature phase signals, providing a sensitivity of 16
mrad/με with a resolution of 1.9 με.
