Latest Patents

One of Nak Hyoun Sung's latest patents is an "Apparatus for and method of measuring thickness of materials using the focal length of a lensed fiber." This invention provides a method for measuring the thickness of materials by utilizing the focal length of a lensed fiber. The lensed fiber generates a Gaussian Beam that moves vertically with respect to the material. The strength of the beam reflected from the material is detected when the beam emitted from the lensed fiber is focused on the material. The thickness of the material is then calculated based on the detected strength of the reflected beam.

Another notable patent is the "Figure-8 optical fiber pulse laser using a dispersion imbalanced nonlinear optical loop mirror." This invention produces stable femto-second optical pulses using a dispersion imbalanced nonlinear optical loop mirror (DI-NOLM). Unlike traditional designs, the optical amplifier is not included in the DI-NOLM but is located at the unidirectional linear loop part. This design reduces noise caused by the bidirectional gain difference of the optical amplifier. The invention employs two optical fibers with different dispersion values, enhancing the switching characteristics of the laser. The stable femto-second laser developed through this invention has numerous applications, including high-speed reaction measurements, laser treatments, and medical lasers.
