Patents by Inventor Flora Ho

Flora Ho has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7289701
    Abstract: A platform for converting a signal between optical and electrical form and vice versa is provided. The platform includes a dielectric mount, a semiconductor light source and optical fibers. Some of these components are fabricated separately and then brought together in an integrated assembly together with a focusing lens. The platform permits the self-alignment of the optical fibers in a flip-chip vertical cavity surface emitting laser (VCSEL) array module package. The self-alignment of the optical fibers is achieved by the engineering of the geometrical dimensions of the platform. The techniques may be used to form large-scale integrated opto-electronic circuits and switching networks.

  • Patent number: 6869230
    Abstract: An optical assembly is provided that is capable of high speed operation using a vertical cavity laser such as a vertical cavity surface emitting laser (VCSEL). The optical assembly is configured to have a small form factor and uses an angled surface of an embedded fiber to internally reflect a beam from the VCSEL along the length of the fiber. The angled surface is coated to ensure that a small portion of the beam is transmitted through the fiber out of the angled surface into a monitoring diode. This geometry provides high coupling efficiency and facilitates direct active alignment between the fiber and the VCSEL.
