High‐Efficiency Graphene‐Silicon Slot‐Waveguide Microring Modulator at 1.5 and 2 µm Wavelength Bands
Laser &Photonics Reviews, EarlyView.E/O modulators typically face a trade‐off between bandwidth and modulation efficiency. An integrated E/O modulator is presented that simultaneously achieves wideband, large bandwidth, and high modulation efficiency operation by embedding a partially overlapped double‐layer graphene on a compact silicon slot‐waveguide microring resonator.
