Patent number: 7013056Abstract: A bi-directional transceiver, integrated module based on a silicon optical bench is provided, which comprises at least a laser diode, at least a signal detector, at least a thin film filter, at least an optical lens, an optical fiber and an SiOB. As the optical signal of specific wavelength can be reflected or inserted by thin film filter, the module has functions of a wavelength division multiplexer and a bi-direction transceiver. Furthermore, the optical lens improves the coupling efficiency between the laser diode and the optical fiber. On the other hand, a plurality of optical elements are integrated on the same SiOB. Hence, only a single optical fiber is used and optical signals of multiple wavelengths can be handled simultaneously.Type: GrantFiled: February 4, 2004Date of Patent: March 14, 2006Assignee: FOCI Fiber Optic Communications, Inc.Inventors: Song-Fure Lin, Pin-Sung Wang, Chien-Hsiung Chiu, Li-Jen Liu

Patent number: 7010190Abstract: The present invention discloses an optic based wavelength division multiplexer device made by a micro lithography and etching process, utilizing the special crystal lattice structure of a silicon wafer. The device comprises a silicon substrate with grooves, an input fiber optic of incoming port with its front lens, a fiber optic of pass port with its front lens, a fiber optic of reflect port with its front lens, and a thin-film filter. The fiber optics, lenses, and the thin-film filter are inserted into grooves to complete the fiber-to-fiber alignment and coupling. The present invention provides both functions of wavelength multiplexing and wavelength demultiplexing. The present invention also has the characteristics of automatic alignment and passive alignment.Type: GrantFiled: December 5, 2003Date of Patent: March 7, 2006Assignee: FOCI Fiber Optic Communications, Inc.Inventors: Chien-Hsiung Chiu, Chun-Sung Chien, Song-Fure Lin, Pin-Sung Wang

Patent number: 6111695Abstract: An optical circulator having reduced size and low polarization mode dispersion is disclosed. A transparent optical circulator comprises a first birefringent crystal, a first pair of Faraday polarization rotators having two Faraday polarization rotators aligned in parallel with the propagation direction of an optical signal, a second birefringent crystal, a second pair of Faraday polarization rotators similar to the first pair of Faraday polarization rotators, and a third birefringent crystal. The optical circulator with a reflector or an input/output device and the Faraday rotators together reduce the total size of the circulator, increase the number of input/output ports, and improve the propagation quality of the optical signal by decreasing the polarization mode dispersion. A reflective optical circulator is also presented.Type: GrantFiled: August 13, 1998Date of Patent: August 29, 2000Assignee: FOCI Fiber Optic Communications, Inc.Inventors: K.
