    Abstract: PROBLEM TO BE SOLVED: To provide a mode conversion device that is configured to facilitate efficient coupling of optical signals passing between an optical part having a different mode field from the device and/or another waveguide. SOLUTION: The device for altering the mode field of the optical signals includes: a pigtail fiber 22; a GRIN fiber lens 24 which is directly splice-joined to one end of the pigtail fiber 22 and has a larger outer diameter than that of the pigtail fiber 22; and a reflection surface 26 which is arranged to one end of the GRIN fiber lens 24. An additional reflection element 36 may be arranged on the reflection surface 26 by fixing or other methods. An optical beam path 38 is emitted from the core 40 of the pigtail fiber 22 and is re-orientation toward a curved surface 34 at the reflection surface 26. The curved surface 34 forms a conic surface, condenses beams along one axis and functions as a cylindrical lens in order to avoid condensation along the other axis. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: Single mode optical fiber waveguides with reduced bending losses for wavelength range of 1300 nm to 1700 nm are disclosed. The extended ranges are achieved by altering the optical characteristics of the fiber, namely, the MAC number, the mode field diameter ("MFD"), and the cut-off wavelength. The single mode fibers disclosed exhibit a lower MFD and higher cut-off wavelength. In addition, optical fiber transmission systems, wave division multiplexing ("WDM") systems, and optical fiber ribbon cables are disclosed that incorporate the single mode optical fiber. Figure 2 shows the refractive index profile as a function of the fiber radius. Figure 6 illustrates a ribbon cable (700) with 4 fibers in a matrix material (708). Each fiber consists of a central core (702), a cladding layer (703), a primary (704) and a secondary polymer layer (705) and a colored ink coating layer (706).

    Abstract: Particular embodiments of the present disclosure bring an SHG crystal, or other type of wavelength conversion device, into close proximity with a laser source to eliminate the need for coupling optics, reduce the number of package components, and reduce package volume. According to one embodiment of the present disclosure, an optical package is provided comprising a laser source subassembly comprising a laser base and a wavelength conversion device subassembly comprising a converter base. The bonding interface of the laser base is bonded the complementary bonding interface of the converter base such that the laser output face can be proximity-coupled to the converter input face at an predetermined interfacial spacing x. Additional embodiments are disclosed and claimed.
