Integrated photonic filters based on SiC multilayer structures

► Tunable WDM converters based on SiC multilayer photonic active filters are analyzed. ► Integrated active long,- and short-pass wavelength filters into capacitive band-pass filters. ► The photonic device combines the demultiplexing operation with the simultaneous photodetection and self amplification of an optical signal. ► The wavelength background and irradiation side control the filter characteristics. ► A numerical simulation and a two building-blocks active circuit are presented.
