Fast thermal relaxation in cavity-coupled graphene bolometers with a Johnson noise read-out
D. K. Efetov, R. -J. Shiue, Y. Gao +10
Since the invention of the bolometer, its main design principles relied on efficient light absorption into a low-heat-capacity material and its exceptional thermal isolation from t…
Ultrafast Graphene Light Emitter
Young Duck Kim, Yuanda Gao, Ren-Jye Shiue +17
Ultrafast electrically driven nanoscale light sources are critical components in nanophotonics. Compound semiconductor-based light sources for the nanophotonic platforms have been…
Chalcogenide Glass-on-Graphene Photonics
Hongtao Lin, Yi Song, Yizhong Huang +16
Two-dimensional (2-D) materials are of tremendous interest to integrated photonics given their singular optical characteristics spanning light emission, modulation, saturable absor…
Self-aligned local electrolyte gating of 2D materials with nanoscale resolution
Cheng Peng, Dmitri K. Efetov, Sebastien Nanot +8
In the effort to make 2D materials-based devices smaller, faster, and more efficient, it is important to control charge carrier at lengths approaching the nanometer scale. Traditio…
High-Responsivity Graphene-Boron Nitride Photodetector and Autocorrelator in a Silicon Photonic Integrated Circuit
