Latest Patents
One of Hansuek Lee's latest patents is a stabilized microwave-frequency source. This invention comprises a dual optical-frequency reference source, an electro-optic sideband generator, an optical bandpass filter, an optical detector, a reference oscillator, an electrical circuit, and a voltage-controlled oscillator (VCO). The sideband generator modulates dual optical reference signals to generate sideband signals. The bandpass filter transmits these sideband signals, while the optical detector generates a beat note. The beat note and a reference oscillator signal are processed to generate a loop-filtered error signal for the VCO. The output of the VCO drives the sideband generator, forming the microwave-frequency output signal. This innovative design results in reduced phase noise on the microwave-frequency signal.
