چکیده:

Abstract- In this paper, a double optical ring resonator is used to demonstrate theoretically an optical filter response, that is based
on phase shift in a Sagnac interferometer. The given filter structure permits the Sagnac rotation to control the filter response. It is
shown that by changing the Sagnac rotation rate, we can tune the filter response for desired wavelengths. To increase the
wavelength selectivity of the filter, the phase shift should be as small as possible. For =۰٫۱ rad., the obtained FWHM is 220 GHz.
