Latest Patents
One of Hu's latest patents is a magnetic-field-tunable terahertz optoelectronic transducer. This invention provides optoelectronic transducers that convert femtosecond (fs)-timescale laser pulses into alternating current (a.c.) electrical current pulses with extremely high frequencies and quality factors (Q). The frequency and amplitude of the a.c. electrical current pulse can be dynamically adjusted by applying a varying bias magnetic field. The transducers are based on a trilayered freestanding membrane that serves as both an acoustic cavity and a magnon cavity. This innovative design includes an electrical conductor layer, a magnetic insulator layer, and a dielectric layer arranged in a vertical stack.
Another notable patent involves magnonic electromagnetic radiation sources with high output power at high frequencies. This invention includes acoustically mediated pulsed radiation sources and phased arrays that utilize these sources to generate electromagnetic radiation through magnetic dipole emission. The radiation sources are based on a superlattice heterostructure that supports in-phase magnetic dipole emission from a series of magnetic insulator layers along the length of the heterostructure.
