With a total of 4 patents, his work has pushed the boundaries of technology in the submillimeter-wave and terahertz frequency ranges.

Latest Patents

One of his latest patents is focused on on-chip diplexed multi-band submillimeter-wave/terahertz sources. This solid-state device chip includes diodes that generate higher or lower frequency outputs through frequency multiplication or mixing of the input frequency. The innovative on-chip diplexing design allows for the combination of multiple multiplier or mixer structures operating at different frequency bands within the 50-5000 GHz range on the same chip or waveguide. This design consists of a single-substrate multiplier chip with multiple structures, each containing Schottky diodes tuned to specific portions of the target frequency band. This results in a significant increase in bandwidth from 10-15% to at least 40%. Depending on the target frequencies, the diodes can be designed to function as either doublers or triplers.

Another notable patent involves high power W-band/F-band Schottky diode-based frequency multipliers. This device chip also includes diodes that generate higher frequency outputs through frequency multiplication. The novel on-chip power combining design enhances efficiency, as the diodes' anodes are micro-fabricated simultaneously on the same GaAs wafer under identical conditions. The optimized GaAs heterostructure and overall chip geometry are designed for high power operation, allowing the device to achieve record-setting power with a signal frequency in the F-band and W-band, boasting a conversion efficiency of 30%.
