Large modulation capacity in graphene-based slot modulators by enhanced hybrid plasmonic effects

Abstract: We present an effective scheme to improve the modulation capacity in graphene-based silicon modulator by employing the double slots configuration with hybrid plasmonic effects. Two modulators, i.e., metal-insulator-metal and insulator-metal-insulator configurations have been demonstrated, showing that the double slots design can significantly improve the modulation efficiency. The obtained modulation efficiency is up to 0.525 dB/μm per graphene layer, far exceeding previous studies. It can be found that the li… Show more

“…Many other efforts have been made to improve the performance of waveguide-integrated graphene electro-optic modulators by using different waveguide configurations, including graphene-on-silicon slot waveguides [54,55] , graphene-embedded waveguides [88,89] , and mode engineering [90] . Therefore, it can be expected that FOMs of waveguide-integrated electrooptic modulators with 2D materials will be continually improved toward realistic applications after exploring new structures and materials.…”

“…The PlasMOStor-based signal modulation is made by exploiting the fast modulation of accumulation conditions in the MOS capacitor, reaching modulation ratios around 10 dB. More recently, the unique optical properties of graphene [138][139][140] are also calling research attention to boost modulation performance, speeds, and optical bandwidths [141,142]. An approach for these graphene-based plasmonic modulators considers a capacitive graphene-insulator-graphene double layer in between two insulator-metal-insulator (IMI) platform [141], as depicted in Figure 3c.…”

“…Graphene, a crystalline of allotropy of carbon with two dimensions, can exhibit a large diversity of physical behaviours ranging from wide band insulator to narrow gap semiconductor to semi-metal or metal. It offers aggravating opportunities for multifarious photonics and optoelectronics function enabling new conceptual photonics devices based on conventional bulk materials (18) (19) .…”
