High-contrast optical filtering is demonstrated using cascaded silicon microrings. We report an experimental measurement of a record 100 dB pass-band to stop-band contrast, tunable 12–125 GHz passband full-width at half-maximum, band-center insertion loss ripple <formula formulatype="inline"><tex Notation="TeX">${<}{3}~{\rm dB}$</tex></formula>, and a group delay ripple <formula formulatype="inline"> <tex Notation="TeX">${<}{5}~{\rm ps}$</tex></formula>, using transverse electric polarized… CONTINUE READING
