Giant nonlinear optical chirality in twisted heterobilayers
Xiang Zhang, Bo Li, Leyi Zhao +7
Twisting two dissimilar monolayer semiconductors induces structural chirality that remains largely elusive in linear optics but becomes remarkably pronounced in the nonlinear regim…
Graphene oxide: new opportunities for optoelectronic, electronic and photonic chips
David Moss
As a derivative of graphene, graphene oxide (GO) was initially developed by chemists to emulate some of the key properties of graphene, but it was soon recognized as a unique mater…
Exciton-plasmon Coupling and Electromagnetically Induced Transparency in Monolayer Semiconductors Hybridized with Ag Nanoparticles
Zhao Weijie, Wang Shunfeng, Liu Bo +9
Hybrid systems of excitons strongly coupled to localized surface plasmons supported by metallic nanoparticles define a new approach to control light-matter interactions. Here, we r…
Generation of 30-fs pulses from a diode-pumped graphene mode-locked Yb:CaYAlO4 laser
Jie Ma, Haitao Huang, Kaijie Ning +5
Stable 30 fs pulses centered at 1068 nm (less than 10 optical cycles) are demonstrated in a diode pumped Yb:CaYAlO4 laser by using high-quality chemical vapor deposited monolayer g…
Graphene-enhanced, internal-magnetic-field-generated Rabi oscillations in metal-coated Si-SiO2 photoconductive detectors
Venkatram Nalla, Kai Zhang, Kian Ping Loh +1
We report our demonstration of Rabi oscillations in Si-SiO2-Al photoconductive devices with nanosecond laser pulses of a few nJ at room temperature without external magnetic fields…
Achieving Giant Magneto-optic Effects with Optical Tamm States in Graphene-based Photonics
Haixia Da, Cheng-Wei Qiu, Qiaoliang Bao +3
We manipulate optical Tamm states in graphene-based photonics to achieve and steer large magneto-optical effects. Here we report the presence of a giant Faraday rotation via a sing…
