Query: Broadband energy-efficient optical modulation by hybrid integration of
  silicon nanophotonics and organic electro-optic polymer   Silicon-organic hybrid integrated devices have emerging applications ranging
from high-speed optical interconnects to photonic electromagnetic-field
sensors. Silicon slot photonic crystal waveguides (PCWs) filled with
electro-optic (EO) polymers combine the slow-light effect in PCWs with the high
polarizability of EO polymers, which promises the realization of
high-performance optical modulators. In this paper, a broadband,
power-efficient, low-dispersion, and compact optical modulator based on an EO
polymer filled silicon slot PCW is presented. A small voltage-length product of
V{\pi}*L=0.282Vmm is achieved, corresponding to an unprecedented record-high
effective in-device EO coefficient (r33) of 1230pm/V. Assisted by a backside
gate voltage, the modulation response up to 50GHz is observed, with a 3-dB
bandwidth of 15GHz, and the estimated energy consumption is 94.4fJ/bit at
10Gbit/s. Furthermore, lattice-shifted PCWs are utilized to enhance the optical
bandwidth by a factor of ~10X over other modulators based on
non-band-engineered PCWs and ring-resonators.
