Waveguide-integrated black phosphorus photodetector with high responsivity and low dark current
Nathan Youngblood, Che Chen, Steven J. Koester +1
Layered two-dimensional materials have shown novel optoelectronic properties and are well suited to be integrated in planar photonic circuits. For example, graphene has been utiliz…
Multifunctional graphene optical modulator and photodetector integrated on silicon waveguides
Nathan Youngblood, Yoska Anugrah, Rui Ma +2
For optical communication, information is converted between optical and electrical signal domains at a high rate. The devices to achieve such a conversion are various types of elec…
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…
