Latest Patents

Higo's latest patents include a method of manufacturing integrated optical pick-ups. In this innovation, light emitted from a light-emitting element is transmitted through a first beam splitter film with polarization selectivity. This process produces a zero-order diffraction beam and two first-order diffraction beams, which are then applied in a condensed manner to an optical disk through a condensing element. The return light beam from the optical disk is directed to a photodetector through a second beam splitter film, facilitating the recording and reproduction of information, as well as tracking and focusing. A diffusion angle conversion hologram is also incorporated, ensuring that the light incident on the condensing element is free from wave aberration, allowing for an ideal spherical wave. This results in a diffraction-limited image spot on the optical disk, enhancing the quality of the RF signal, focus error signal, and track signal.
