Title: Myoung Hoon Song: Innovator in Laser Technology
Introduction
Myoung Hoon Song is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of laser technology, holding a total of 2 patents. His innovative work focuses on enhancing the efficiency of laser oscillation elements and optical diodes.
Latest Patents
One of his latest patents is for a laser oscillation element. This invention comprises a cholesteric liquid crystal layer containing cholesteric liquid crystals, with another cholesteric liquid crystal layer facing it. A defect layer containing a dye that emits fluorescence upon optical excitation is disposed between these layers. The selective reflection wavelength band in the cholesteric liquid crystals overlaps with the emission band of the fluorescence emitted by the dye. The helical winding directions of the cholesteric liquid crystals are identical, and the transition moments of the dye are aligned parallel to the surfaces of the cholesteric liquid crystal layers. This design allows for high-efficiency laser oscillation and the generation of continuous wave lasing.
Another significant patent by Myoung Hoon Song is for an optical diode. This device features a cholesteric liquid crystal (CLC) layer with a selective reflection wavelength band that has a left-handed helical structure. It includes a phase shifter that changes the phase difference between two intrinsic polarized light components of left-handed circularly polarized light. When this light is incident on the phase shifter, it is converted into right-handed circularly polarized light, which can then be transmitted through the CLC layer. Conversely, left-handed circularly polarized light within the selective reflection wavelength band is selectively reflected by the CLC layer.
