Graphene prototype modulator shown working at 10 Gigabit

- Imec's graphene electro-absorption modulator works at 10 Gigabit-per-second
- The modulator is small and has be shown to be thermally stable
- Much work is required to develop the modulator commercially

Imec has demonstrated an optical modulator using graphene operating at up to 10 Gigabit. The Belgium nano-electronics centre is exploring graphene - carbon atoms linked in a 2D sheet - as part of its silicon photonics research programme investigating next-generation optical interconnect. Chinese vendor Huawei joined imec's programme late last year.
