Radiation-Resistant Er3+-Doped Superfluorescent Fiber Sources

“…Interferometric fiber optic gyroscopes (IFOGs) have potential application in spacecraft and satellite space missions due to their numerous advantages, such as high reliability, long life, light weight, high resolution, as well as stable scale factor [ 1 , 2 , 3 ]. In meeting the requirements of navigation-grade IFOGs, its light source is usually an Er-doped superfluorescent fiber source (SFS) [ 1 , 2 ], whose high-stability mean wavelength and output power can achieve low bias drift and stable scale factor for IFOG application [ 3 ].…”

“…Interferometric fiber optic gyroscopes (IFOGs) have potential application in spacecraft and satellite space missions due to their numerous advantages, such as high reliability, long life, light weight, high resolution, as well as stable scale factor [ 1 , 2 , 3 ]. In meeting the requirements of navigation-grade IFOGs, its light source is usually an Er-doped superfluorescent fiber source (SFS) [ 1 , 2 ], whose high-stability mean wavelength and output power can achieve low bias drift and stable scale factor for IFOG application [ 3 ]. However, in space applications, various space rays and ionizing radiation can remarkably affect the radiation-induced attenuation (RIA) of SFSs, which in turn can cause mean wavelength drifts and power attenuation [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ].…”

“…Most of the previous researches have been devoted to improving the radiation-resistant capabilities of SFSs [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ]. The output power loss of SFSs can be mitigated by the Erbium-doped fiber (EDF) radiation-tolerant design and processing [ 13 , 14 , 15 , 16 , 17 , 18 , 19 ].…”

“…The output power loss of SFSs can be mitigated by the Erbium-doped fiber (EDF) radiation-tolerant design and processing [ 13 , 14 , 15 , 16 , 17 , 18 , 19 ]. The loss can be further suppressed by the feedback control of the pump power [ 3 , 4 ]. On the other hand, the RIA-induced mean wavelength drift of an SFS can be effectively lowered by tailoring the spectrum [ 3 , 6 , 11 , 12 , 20 ], which is mainly achieved through filtering strategy, such as edge filter [ 3 ], band filter [ 6 ], and Gaussian filter [ 12 , 20 ].…”

Despite considerable research effort, the overall radiation-resistant performance of the SFS is far from state-of-the-art.…”
