A fully electrically tunable microwave photonic filter is realized by the implementation of delay lines based on frequency-time conversion. The frequency response and free spectral range (FSR) of the filter can be engineered by a simple electrical tuning of the delay lines. The method has the capability of being integrated on a silicon photonic platform. In the experiment, a 2-tap tunable microwave photonic filter with a 3-dB bandwidth of 2.55 GHz, a FSR of 4.016 GHz, a FSR maximum tuning range from -354 MHz to 354 MHz and a full FSR translation range is achieved.
通过基于频率-时间转换实现延迟线，实现了一种完全电调谐的微波光子滤波器。通过对延迟线进行简单的电调谐，可以设计滤波器的频率响应和自由光谱范围（FSR）。该方法具有集成到硅光子平台上的能力。在实验中，实现了一个两抽头可调谐微波光子滤波器，其3分贝带宽为2.55吉赫兹，FSR为4.016吉赫兹，FSR最大调谐范围为-354兆赫兹至354兆赫兹，全FSR平移范围也得以实现。
