    Modified nested MZI[1] advised by Ref. [30]. An inner MZI is nested into one arm of an outer MZI. Three Dove prisms are placed in all three arms of the nested MZI, and the orientation of the prism near mirror A is different from that of the other two.

    (a) The photon traces passing through the Dove prisms along paths II and III, in which the relative position of the laser ray (green dotted line) with mirror E tilting does not change compared to the original ray (red solid line) without mirror E tilting. (b) The photon traces passing through the Dove prism along the path I, in which the relative position of the laser ray (green dotted line) with mirror E tilting changes compared to the original ray (red solid line) without mirror E tilting.
