摘要：

An electrically controlled filter for the dynamic selection of channels in DWDM optical network is proposed. The device is realized by combining the electrical injection of free carriers with a Bragg grating realized over the top of a Silicon on Insulator RIB waveguide. Apodization of the duty-cycle of the grating has been investigated in order to reduce the crosstalk between adjacent channels; in this way the performances of the filter in terms of spectral bandwidth for 100 and 50 GHz DWDM spacing become attractive.
