Electronics Letters
Preserved Fulltext
A tunable and polarisation-maintaining all-in-fibre filter based on a liquid crystal photonic bandgap fibre is demonstrated. Its polarisation extinction ratio reaches 14 dB at 1550 nm wavelength. Its spectral tunability range spans over 250 nm in the temperature range 30 -708C. The measured transmission spectrum is compared with that obtained through finite element simulations.
