Paper Abstract

A novel filter with tunable bandwidth and wavelength is introduced. Its bandwidth can be tuned by a transverse voltage. And its wavelength can be tuned by a longitudinal voltage. The main parameters that affect its properties are synthetically analyzed. Computer simulation results show that its transmission bandwidth is changeable and the transmission spectrum with rectangular working area is close to the ideal band-pass function. Experimentally, its free spectral range is more than 50nm. The tunable range of the center wavelength is about 50nm. The full width at half maximum can be tuned from 1.2nm to 50nm.
