Independent tuning of cascaded long period fibre gratings (LPFGs) is demonstrated. This involves applying a small controllable bend to each LPFBG, resulting in a synthetic spectral response due to the spectral overlap. This technique provides high spectral shaping flexibility coupled with high sensitivity and a wide tuning range
