摘要：

We demonstrate a THz bandpass filter (BPF) made from high-temperature (T-c) superconducting Bi2Sr2CaCu2O8+delta (BSCCO). The filter offers a thermally tunable dual passband with a flat response in the first passband, a bandwidth of similar to 0.33 THz, and a sharp resonance band-edge transition to the rejection bands of similar to 316 and 96 dB/THz (for left and right edge, respectively), at temperature T=10 K far below Tc. As temperature T increases, the sharpness of the band-edge transition to the rejection bands decreases. The proposed BPF can be useful in the realization of a superconducting based THz integrated circuitry.
