Abstract
Tunable, narrowband transmission notches are opticaily induced in the bandgap of permanent optical fibre Bragg gratings, which have been highly doped with Er3+ ions to provide a strong resonant nonlinear refractive index. A 10 dB contrast in transmission is achieved with a 50 µW change in pump power incident on the core.Keywords
