Abstract :
A tunable Gaussian filter based on a tapered liquid crystal photonic bandgap fibre is presented. The filter is centred at lambda=1062 nm and has a 3 dB bandwidth of 150 nm. Tunability is achieved by exploiting the thermo-optic effect of the liquid crystals. A shift of 110 nm at the central wavelength is observed by increasing the temperature from 30 to 80degC
