title: Nearly arbitrary on-chip optical filters for ultrafast pulse shaping.
abstract: We demonstrate a reverse design method for realizing a broad range of optical filters based on integrated optical waveguides and experimentally verify example designs on a CMOS-compatible silicon-on-insulator (SOI) platform. The reflectance-based filters allow for control of both phase and amplitude of the optical response. Among this device's many potential applications we highlight and numerically demonstrate its use for ultrafast on-chip pulse shaping.
