摘要： The present invention is directed to the creation of optical waveguiding devices from standard optical fibers by the creation of zones of permanently altered refractive index characteristics therein. A high intensity femtosecond laser beam is focused at a predetermined target region in the fiber so as to soften the glass material at the target region. After aligning the focal region with the target region in the fiber there will be relative movement between the focal region and the fiber, which has the effect of sweeping the focal region across the fiber in a predetermined path, so as to create a secondary waveguide path. A portion of the light traveling along the core is removed from the core along the secondary waveguide path such that the device can be utilized as an attenuator, an optical tap, or a polarimeter.

摘要： A method is disclosed wherein optical structures such as Bragg gratings can be written into planar waveguides disposed on a substrate. By employing the method of this invention, a polarization insensitive device can be made. Such relatively thin planar waveguides disposed on a substrate are inherently polarization sensitive and the structure itself is birefringent. By writing structures in the waveguides or by simply writing a refractive index change in the waveguide by limiting the beam width at the waveguide layer to less than or equal to the thickness of the waveguiding layers on the substrate, in combination with conventional wider beam writing techniques, polarization sensitivity can be lessened or obviated.

摘要： Disclosed are optical data bus configurations for interconnecting terminals so that any terminal can communicate with any other terminal. It is known to do this by connecting terminals serially using two trunk optical fibers and to connect terminals together in a star configuration using a single transmission star or reflection star. The serial network is limited by optical loss while the star network requires more optical fiber and is more costly. Disclosed is a serial bus which uses six fibers arranged in two groups of 3 each, the groups conducting light in mutually opposite directions. A transmitting means in each terminal is coupled to two of the fibers in each group and terminals adjacent any one terminal are connected to a different two fibers than the one terminal. Another arrangement disclosed uses hybrid reflection-transmission star couplers. Terminals can be connected to reflection ports of the hybrid couplers, while the couplers can be interconnected by the transmission ports thereof. A relatively small number of fibers are required to interconnect a large number of terminals.

摘要： Unbalanced Mach-Zehnder interferometers (MZI) are useful for a number of applications including wavelength filters, gain flattening or gain equalization elements, and band splitters or combiners. A MZI is comprised of two couplers surrounding a phase shifting region, which consists of two arms with differential propagation constants. We disclose a means of using light exposure to unbalance a symmetric MZI consisting of substantially the same lengths of substantially the same fiber. In particular, the index of refraction of a fiber can be increased by exposure to ultraviolet light, and the magnitude of the change can be increased by using higher germanium doping or by hydrogen loading the fiber. The magnitude of the phase shift can be controlled accurately by varying the fiber length exposed, the light exposure intensity, the light exposure time, and the hydrogen loading or fiber composition. In addition, exposing the other arm,of the MZI to trim back the phase shift can compensate any over-exposure of the fiber. By starting with a symmetric MZI made from substantially the same fiber, low polarization sensitivity or polarization dependent loss can be achieved, and the device can operate over a wider overall wavelength range. Also, by using a MZI with substantially the same lengths of fibers and by placing those fibers parallel to one another, low environmental sensitivity can be achieved. Moreover, the use of light exposure to unbalance the MZI has the advantage of enabling precise tailoring of the spectral response with ease of manufacturing and high yields. The MZI devices can be cascaded to achieve more complicated filtering functions in lattice devices such as Lyot-Ohman filters or Solc filters.
