The double slot graphene photodetector offers a high responsivity of 603.92mA/W and a large bandwidth of 78GHz, offering a competitive solution for photodetection on silicon. (Image OEA)
The double slot structure could also be applied to a broader range of hybrid two-dimensional material/silicon device

As microscopes become ever more powerful, a growing band of businesses are racing to make the latest technologies more accessible and more affordable, reports Rebecca Pool
Illustration of a three-dimensional crystal with various types of confining centres. (a) Crystal with four confining centres, each trapping waves (yellow) in all three dimensions simultaneously. (b) Crystal with a linear confining centre where waves can propagate in one dimension, analogous to an optical fibre. (c) Crystal with a planar confining centre where waves can propagate in two dimensions, analogous to a 2D electron gas. (Image: Vos et al.)
Newly discovered fundamental rules have been embedded into software to dramatically optimise the design of photonic integrated circuits
