Lai, Y., Zhang, W., Zhang, L., Williams, J.A.R. and Bennion, I. (2003). An optical pump controlled tunable phase-shifted fiber grating transmission filter. IN: Optical Fiber Communications Conference, 2003. Sawchuk, A.A. (ed.) Techincal digest, 1 . IEEE.


Optical pump controlled, remotely tunable phase-shifted fiber grating transmission filters were analyzed. The transmission peak had a full width hail maximum (FWHM) bandwidth. With increasing control pump power, the resonant peak shifted towards the longer wavelength side. The efficiency of the system was largely affected by the greater number of sections of doped fiber as well as the absence of recirculation of unabsorbed pump beam. The configuration, besides its simplicity and cost-effectiveness, exhibited wavelength-independent pump-induced phase shifts and no anisotropic effects during operation.
