Graphene research so far has focused on electronic1,2,3,4,5,6 rather than photonic applications, in spite of its impressive optical properties7,8. These include its ability to absorb ∼2% of incident light over a broad wavelength range despite being just one atom thick7. Here, we demonstr...
Hybrid graphene-quantum dot architectures can greatly improve responsivity(13), but at the cost of response speed. Here, we demonstrate a waveguide-integrated graphene photodetector that simultaneously exhibits high responsivity, high speed and broad spectral bandwidth. Using a metal-doped graphene ...
Graphene pushes the speed limit of light-to-electricity conversion: Researchers from ICFO, MIT and UC Riverside have been able to develop a graphene-based photodetector capable of converting absorbed light into an electrical voltage at ultrafast timescales Barcelona, Spain | Posted on April 14th, 20...
[1]These properties make graphene an attractive candidate for various applications,such as ultracapacitors,[6,7]solar cells,[8–11]photodetector,[12]and low-power-consumption electronics.[13,14]However,the lack of a bandgap limited its application in logic electronic devices.Furthermore,its ...

temporal alteration of photodetector's characteristics - such as responsivity and detectivity as well as response time and response spectral bandwidth. However, with excessive energy transfer that can follow bleaching the effect may be masked by thermal noise or even lattice disorder. In this paper we...
Laser state active controlling is challenging under the influence of inherent loss and other nonlinear effects in ultrafast systems. Seeking an extension of degree of freedom in optical devices based on low-dimensional materials may be a way forward. Herein, the anisotropic quasi-one-dimensional layer...
