Patent number: 7577321Abstract: A hybrid electro-optical circuit board including a plate, a light guiding hole and a light-guide device. The light guiding hole is formed in the plate to be connected to an upper surface and a lower surface of the plate. The light-guide device is formed on the lower surface and covers and contacts the light guiding hole. An optical signal is transmitted between the light-guide device and the upper surface of the plate via the light guiding hole. A metal layer is further formed on an inner wall of the light guiding hole, to reduce the roughness of the inner wall and reflects the optical signal by the reflection characteristics of metal. Further, the light guiding hole is filled with a transparent substance to transmit the optical signal and to stop foreign material from entering the light guiding hole.Type: GrantFiled: April 26, 2007Date of Patent: August 18, 2009Assignee: Industrial Technology Research InstituteInventors: Chien-Chun Lu, Shin-Ge Lee, Chun-Hsing Lee, Shun-Tien Lee, Ying-Chih Chen

Patent number: 7489872Abstract: The present invention is an optical fiber system and method for carrying both CATV and Ethernet signals. The digital signals are translated into higher band by a direct up/down conversion so that analog signals and digital signals are treated as different frequency bands of electrical signals. Then, all the signals are mixed/divided by a power combiner/divider. And then, by using optoelectronic devices, the signals are processed with optoelectronic conversion. The converted optical signals are transmitted in a fiber or a related optical channel having low channel loss yet high capacity. To sum up, the present invention can transmit digital signals together with analog signals in a single wavelength to save the cost of an optical signal system and to provide a convenience on rearranging the system.Type: GrantFiled: September 24, 2004Date of Patent: February 10, 2009Assignee: National Central UniversityInventors: Yi-Jen Chan, Fan-Hsiu Huang, Hsin-Pin Wang, Dong-Ming Lin, Mu-Tao Chu, Shin-Ge Lee, Shun-Tien Lee
