Query: Miniaturized Low-power Electro-optic Modulator Based on Silicon
  Integrated Nanophotonics and Organic Polymers   We design and demonstrate a compact, low-power, low-dispersion and broadband
optical modulator based on electro-optic (EO) polymer refilled silicon slot
photonic crystal waveguide (PCW). The EO polymer is engineered for large EO
activity and near-infrared transparency. The half-wave switching-voltage is
measured to be V{\pi}=0.97V over optical spectrum range of 8nm, corresponding
to a record-high effective in-device r33 of 1190pm/V and V{\pi} L of 0.291Vmm
in a push-pull configuration. Excluding the slow-light effect, we estimate the
EO polymer is poled with an ultra-high efficiency of 89pm/V in the slot. In
addition, to achieve high-speed modulation, silicon PCW is selectively doped to
reduce RC time delay. The 3-dB RF bandwidth of the modulator is measured to be
11GHz, and a modulation response up to 40GHz is observed.
