我们提出了一种采用非相干宽带光源（BOS）和可编程光谱处理器的复杂抽头微波光子滤波器（MPF）的新颖结构。通过调整光谱幅度和相位，可以构建 MPF 的任意复杂连续时间脉冲响应。分别演示了单个平顶、高线性调频或任意形状通带的频率响应。通带中心也可以在很宽的范围内调谐，仅受光电器件的限制。据我们所知，这是基于非相干 BOS 的 MPF 的首次演示，该 MPF 是单带通、广泛可调且具有复杂抽头的高度可重构性。
We propose a novel structure of complex-tap microwave photonic filter (MPF) employing an incoherent broadband optical source (BOS) and a programmable optical spectrum processor. By tailoring the optical spectral amplitude and phase, arbitrary complex continuous-time impulse responses of the MPF can be constructed. Frequency responses with a single flat-top, highly chirped, or arbitrary-shape passband are demonstrated, respectively. The passband center can also be tuned in a wide range only limited by the opto-electrical devices. To the best of our knowledge, it is the first demonstration of an incoherent-BOS-based MPF which is single-bandpass, widely tunable, and highly reconfigurable with complex taps.
