“…Although we have analyzed the case of non-reciprocity induced by moving media, a similar phenomenon can be expected in non-reciprocal optical devices realized by magnetoplasmonic structures [31,32], or by recently reported opto-mechanically induced non-reciprocity [33,34]. Such motion induced non-reciprocity is widely used in Fiber Optic Gyroscopes (FOG) [35] and is still an active area of research [36][37][38]. Recently, Weernink et al have studied forces induced by breaking time-reversal symmetry in a rotating particle near a planar surface [39] and similar systems can be used to verify our theoretical predictions.…”

Optical forces acting on particles - controlled by the intensity, polarization and direction of optical beams - have become an important tool in manipulation, sorting and analysis of nano/micro-particles. The nature of these forces has been well understood in reciprocal structures exhibiting time-reversal symmetries. Here, we investigate the nature of optical forces in non-reciprocal structures with non-degenerate counter-propagating modes. We consider the specific case of non-reciprocity induced via translational motion and show that the two counter-propagating modes in a moving slab-waveguide are not degenerate which results in a non-zero lateral and longitudinal force on a nanoparticle. We prove that these anomalous forces are fundamentally connected to near-field photonic spin in optical waveguides and explain their directionality using universal spin-momentum locking of evanescent waves. The presented results show that the interplay of photon spin and non-reciprocity can lead to unique avenues of controlling nanoscale optical forces on-chip.

“…The optical routing is composed of light source, multifunction integrated optic circuit (MIOC), and fiber-optic coil. The MIOC is used for splitting, polarizing and phasemodulating [16], [26], [27]. The light source outputs light waves with wavelength stability and high power.…”

In practical, the Faraday effect-induced bias error is one of the main sources of bias error for the interferometric fiber optic gyroscope (IFOG). The Faraday effect-induced bias error impairs in the performance of IFOG. Normally, the Faraday effect-induced bias errors is hardly eliminated. To improve the performance of IFOG, the accurate model of Faraday effect-induced bias errors is necessary for its practical applications. In this paper, from the perspective of the finite element method, we calculate Faraday effect-induced bias errors of the fiber coil by the three-dimensional model in the radial magnetic field and the axial magnetic field. Comparing with the traditional model, the differences mainly come from the size and direction of the magnetic field, including the differences of the twist ratio and the bending rate of each layer. Using the Jones matrix, we derive the three-dimensional magnetic field error model, further more theoretical results are obtained by simulation. The experiment with a 1024 m PM fiber coil are performed, and the experimental results support these theoretical predictions.

“…In order to improve the performance of FRIs, research works were dedicated to mitigating two types of error sources from perturbations [6]. One is the intrinsic perturbations such as polarization cross-couplings in fibers [7,8] and splicing misalignments between fibers [9,10]. The other is the external perturbations from surrounding environments such as thermal fields [11][12][13], magnetic fields [14][15][16], and thermal stress fields [17][18][19].…”
