A Graphene-caped polymer filled silicon slot waveguide is proposed to enhance the interaction between Graphene layer and propagating optical mode. This is achieved by field intensity enhancement in slot region and consequent optical absorption by Graphene layer. The proposed design is optimized to achieve a low half wave voltage-interaction length product (V_π × L_π) of 0.05 V-cm, low energy consumption (0.61 pJ/bit), 90 micron length, wide 3-dB modulation bandwidth of approximately 197 GHz and a drive voltage in the range of 2.2 V to 7.8 V. This design is compatible with Complementary metal-oxide-semiconductor (CMOS) fabrication standard.
