Latest Patents

One of Kyungwon An's latest patents is for a microlaser. In this invention, a pair of opposed reflectors define a high-finesse or 'high-Q' optical cavity. A source delivers a stream of multiple-energy-level atoms or particles into the cavity. Each individual atom in the stream is excited by a pump from a lower energy level to an upper energy level before being injected into the cavity. The cavity resonance frequency is substantially matched to the frequency of a photon emitted by each atom as it enters the cavity. The photon is emitted due to a transition in energy between the upper level and lower level of each atom. This process allows for the average number of photons resonating in the cavity to exceed one, while the average number of atoms in the cavity remains less than one. The photons are sustained in the high-Q cavity long enough for the photon field to interact with the next atom in the stream, resulting in the emission of a beam of coherent light in the optical frequency spectrum.

Another notable patent is a method for laser-induced fluorescence of tissue. This method utilizes laser radiation to illuminate and induce fluorescence in the tissue under study, allowing for the determination of the chemical composition or pathological condition of the tissue. The laser radiation and the retrieved fluorescing radiation can be conveyed through a catheter using an array of optical fibers. The fluorescence spectrum of the tissue can be displayed and analyzed to obtain valuable information regarding the chemical composition and medical condition of the tissue inside the human body.
