摘要：
A detailed analysis of a microwave reflection pattern that is due to periodically photoexcited layers of semiconductor material in a waveguide is presented. Different photoconductivity profiles that are due to different excitation conditions with different materials are tested. The diffusion of carriers in the direction of propagation can strongly affect the passband-filtering responses, especially the efficiency and the bandwidth. These configurations can be used as light-induced tunable filters and as a variable matching section between different levels of impedances. (C) 1995 Optical Society of America
