本文报道了一种光致分布布拉格反射带阻微波滤波器，其中光栅元件是通过硅共面波导的光激励产生的。频率中心可以通过由六个CW操作的50 mW，840 nm发光二极管（LED）馈电的图案控制光纤束阵列光学调节到11 GHz和22 GHz。实验结果与理论预测吻合较好。所演示的操作原理也适用于毫米波集成电路。>
A light-induced distributed Bragg reflection band-reject microwave filter is reported in which the grating elements are optoelectronically generated through periodic-structure photoexcitation of a silicon coplanar waveguide. The center for frequency can be optically adjusted to 11 GHz and 22 GHz by means of a pattern-controlled fiber bundle Array fed from six CW-operated 50-mW, 840-nm light emitting diodes (LEDs). Experimental results are in good agreement with theoretical predictions. The principle of operation demonstrated also applies to millimeter-wave integrated circuits. >
