title = "Optical bandpass Lyot filter with tunable bandwidth",
abstract = "We experimentally demonstrate the feasibility of the bandwidth tuning of a liquid-crystal based bandpass Lyot filter. This bandwidth tuning is achieved by applying a voltage to vary the birefringence of the liquid-crystal cells whose optical path difference takes predefined discrete values. We show that for a 2-stage liquid-crystal Lyot filter and at λ i = 1.543 μm, the measured 3-dB bandwidth varies from 17nm to 60 nm when the applied voltage increases from 0V to 5.24V. The shape of the transmission response remains unchanged during the bandwidth tuning process.",
