Abstract:
A power switching device includes an optically controlled component using a semiconducting carbon nanotube. An optical signal transmitted over an optical fiber controls the conductivity of the nanotube. The nanotube transmits a signal controlled by the optical signal to a wide-bandgap semiconductor power switch, which switches the power.
