Latest Patents

One of his latest patents is titled "All-optical AM-to-FM up-conversion for radio-over-fiber." This invention involves a laser source configured for all-optical AM-FM up-conversion. In this exemplary embodiment, an amplitude modulated (AM) optical input signal containing a baseband signal at a sub-microwave frequency is injected into the laser source. The amplitude of the AM optical input signal and the optical carrier frequency are adjusted to place the laser source in a period-one dynamical state. This state is characterized by a transition of the laser source from a free-running optical frequency to at least two optical frequencies, resulting in a frequency modulated (FM) optical output signal.

Another notable patent is for a "High-resolution microscope using optical amplification." This invention enhances the resolution of a microscope in all three spatial dimensions. The microscope system includes a first objective lens and an illumination source that provides excitation illumination at a first wavelength. The system also features an element that provides illumination at a second wavelength to the sample and a detector for detecting the fluorescent emission. The optical gain of the fluorescent emission at the second wavelength is enhanced through stimulated emission.
