    Abstract

    We demonstrate a complmentary metal-oxide-semiconductor (CMOS)-compatible and widely tunable filter with an integrated germanium detector. The filter uses two stages of sixthorder pole-zero filtering cascaded in a vernier fashion to achieve simultaneous tunability and adjustable passband bandwidth from 25 to 50 GHz tuned over a wavelength range >12 nm. The out-ofband crosstalk rejection is ∼ 30 dB. The monolithically integrated detector has a bandwidth of 6 GHz. We also demonstrate a modified detector design which showed a bandwidth of 11 GHz/s and responsivity of 0.75 A/W.
