AB  - The objective of this study is to investigate the sensitivity of recirculating delay line (RDL) and Mach-Zender (M-Z) interferometers when an optical amplifier is introduced in the fiber feedback loop. The RDL and M-Z interferometers have a maximum sensitivity to the measurand as well as to any noise variable. However, the M-Z interferometer with a feedback path, the sensitivity to other variables such as the temperature and the wavelength changes, can be eliminated by the common mode compensation. In the study new optical fiber interferometers are analyzed and simulated. The new optical circuits consist of a RDL and a M-Z interferometer with feedback path, where an optical amplifier is introduced in the feedback loop to compensate for the losses due to the couplers and the splices as well as for the attenuation in the fiber itself. The transmittance of the circuit, which is the ratio of the output intensity to the input intensity, is calculated and plotted for different gain factors of the amplifier. Both weak and strong coupling are considered for the coupler
