Petahertz, or lightwave, electronics uses tailored optical waveforms to control charge carriers in an electronic circuit at petahertz frequencies. This may enable faster processing than conventional pulsed electronics, which cannot be scaled beyond gigahertz frequencies.
In their latest review published in Nature Review Physics, Prof. Matthias Kling and his colleagues discuss the progress towards sub-cycle field-driven current injection, highlighting key theoretical concepts, experimental milestones, and questions remaining as they push towards realizing petahertz electronics for ultrafast optical waveform analysis, digital logic, communications, and quantum computation.
