| Abstract: | A tunable bandpass filter is demonstrated by applying a variable thermal gradient to a microstructured fibre with high index inclusion, thus chirping its local anti-resonances. The width of its transmission bands can be continuously varied and transmission completely suppressed. The experiment is compared with numerical simulations. |
