Scientists at The University of Manchester have discovered a new method of creating optoelectronic circuits using graphene and other 2D material much smaller than their current counterparts. Optoelectronics, the technology that uses pulses of light rather than traditional electrical signals, is vital for telecommunication networks.
Modulators are important in optoelectronic circuits as they control the signals passed through optoelectronic devices. Previous attempts to create hybrid modulators incorporating graphene have yielded promising although limited results.
