摘要

Anovel scheme of an ultralowrelative intensity noise (RIN) broadband source module employing a double pumped backward (DPB) Er-doped superfluorescence fiber source (EDSFS) and a semiconductor optical amplifier for interferometric fiber optic gyroscopes (IFOGs) is proposed. With optimized parameters, the optimal twin-peak output profile of the source is obtained. The effective optical spectrum width of the source is 38.6 nm, and the output power is about 12.5mW. Compared with theDPBEDSFS with a similar spectrum, the ultralowRIN broadband source proposed demonstrates a lower RIN of about 8.4 dB. A high-precision IFOG utilizing the ultralow RIN broadband source is set up, and the performance of the IFOG is experimentally studied. An angle random walk coefficient of 6.93 x 10(-50)/h(1/2) is demonstrated, which is reduced by about 31.5% compared with the same IFOG system utilizing conventional DPB EDSFS with a similar spectrum profile. The ultralow RIN broadband source module proposed is quite feasible for high-precision IFOGs used in strategic-grade navigation systems and satellites. (C) 2021 Optical Society of America
