Deep subwavelength plasmonic waveguide switch double graphene layer structure
2015/8/7
Graphene provides excellent prospects of the dynamic tunability, low propagation loss, and extreme mode confinement for plasmonic excitations in the infra-red and terahertz frequencies.We show t...
Passive Mode-Locker Incorporating Physically Exfoliated Graphene for Fiber Ring Lasers
Mode-locked laser Nanomaterials Lasers fiber
2015/5/21
A passively mode-locked fiber laser is realized using an intracavity intensity-modulating effect in multilayered graphene efficiently prepared by taping method. 10.6-MHz pulse trains with 40-dB extinc...
Nonlinearity-Preserved Graphene/PVAc Composite in Optical Deposition for Fiber Mode-Locked Lasers
Nanomaterials Nonlinear optical devices Mode-locked laser
2015/5/21
We demonstrate efficient optical deposition of graphene onto optical fibers preserving its nonlinearity guaranteed by graphene/PVAc composite formation. Passive mode-locking of fiber laser producing p...
Researchers at IBM have made the first photodetector from graphene – a sheet of carbon just one atom thick. The device, which can accurately detect optical data streams at speeds of 10 Gbit/s, could b...
