Compact, High-Speed and Power-Efficient Electrooptic Plasmonic Modulators

摘要: CMOS compatible electrooptic plasmonic modulators are slated to be key components in chip-scale photonic circuits. In this work, we investigate detailed design and optimization protocols for that suitable free-space coupling on-chip integration. The metallic structures the proposed devices offer simultaneous electric optical functions. resonance-enhanced nonlinear interaction submicrometer-footprint of these meet stringent requirements future modulators, allowing high-speed operation (>100 GHz) with a decent modulation depth (>3 dB) moderate insertion loss (<3 at very low swing voltage (∼1 V) power dissipation fJ/bit). realization appears feasible current materials lithographic techniques.
