“…This is because as the linewidth decreases, the coherence length increases and hence the number of scatterers in the fiber contributing coherently to the bias increases. 8 However, once the coherence length of the source exceeds the loop length, the trend changes depending on the propogation loss. For a typical polarization maintaining fiber with 2 dB/km loss, the bias error becomes independent of source bandwidth.…”

“…Navigational grade performance is feasible. Interesting developments include using hollow-core fibre to avoid scattering entirely [23], and a revisiting of the use of high coherence sources whilst maintaining good overall performance [24].…”

“…For the R-FOG, the recent advent of air-core photonic-bandgap fibers (PBFs) offers a radically new means for further reducing all of the above performance degradation simultaneously [16][17][18], as in a PBF the optical mode is mostly confined to the air core, whereas in a conventional fiber, the lightwave travels entirely through silica. Thus, by replacing the solid-core fiber with the PBF in the R-FOG, the R-FOG is still a promising candidate for high grade rotation sensing.…”
