Erbium-doped Superfluorescent fiber source for fiber-optic gyroscope

摘要

The characteristic of Erbium-doped Superfluorescent fiber source was introduced. The double pass backward configuration Superfluorescent fiber source was demonstrated mainly and two wavelength selected reflector, thin file filter and fiber bragg grating, were taken to form two Superfluorescent fiber source. Their whole parameters, including power, spectrum and spectrum width, were tested, the coherence was calculated and the mean wavelength temperature stability is tested too. The result proved the Superfluorescent fiber source with thin film filter and fiber bragg grating are both suitable to inertial grade fiber optic gyroscope.
