Optical absorption in graphene integrated on silicon waveguides
Huan Li, Yoska Anugrah, Steven J. Koester +1
To fully utilize graphene's remarkable optical properties for optoelectronic applications, it needs to be integrated in planar photonic systems. Here, we demonstrate integration of…

High-speed waveguide-coupled graphene-on-graphene optical modulators
Steven J. Koester, Mo Li
An electro-absorption optical modulator concept based upon a dual-graphene layer is presented. The device consists of a silicon-on-insulator waveguide upon which two graphene layer…

Tunable bipolar optical interactions between guided lightwaves
Mo Li, W. H. P. Pernice, H. X. Tang
The optical binding forces between guided lightwaves in dielectric waveguides can be either repulsive or attractive. So far only attractive force has been observed. Here we experim…
