A comprehensive survey of photosensitivity in silica glasses and optical fiber is reviewed. Recent work on understanding the mechanisms contributing to germanium or aluminum doped fiber photosensitivity is discussed within the framework of photoelastic densification models.
Two photoinduced Bragg reflectors at 1480 nm are written at both ends of the fibre amplifier. Above threshold, laser oscillation clamps the gain and suppresses low frequency signal or pump induced gain fluctuations.
