摘要：

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 frequency can be optically adjusted to 11 GHz and 22 GHz, respectively, by means of a pattern-controlled fiber bundle array fed from six CW-operated 50 mW, 840 nm LED's. Experimental results are in good agreement with theoretical predictions. The principle of operation demonstrated also applies to millimeter-wave integrated circuits.
