Abstract
We design and demonstrate a compact and low-power, band-engineered, electro-optic (EO) polymer refilled silicon slot photonic crystal waveguide (PCW) modulator. The EO polymer is engineered for large EO activity and near-infrared transparency. A PCW step coupler is used for optimum coupling to the slow-light mode of the band-engineered PCW. The half-wave switching voltage is measured to be over an optical spectrum range of 8 nm, corresponding to the effective in-device of and in a push–pull configuration. Excluding the slow-light effect, we estimate that the EO polymer is poled with an efficiency of in the slot.
