    摘要: There is provided a polarization maintaining optical fiber coupler and a method of manufacturing this polarization maintaining optical fiber coupler in which manufacturing is simplified and excess loss is reduced. A polarization maintaining optical fiber coupler is provided in which, in at least one of the polarization maintaining optical fibers forming the fused and extended portion, the ratio of the [diameter of the core/the diameter of the cladding] or [the distance between the two stress applying portions/the diameter of the cladding] is greater than the ration of the [diameter of the core/the diameter of the cladding] or [the distance between the two stress applying portions/the diameter of the cladding in the portions of the polarization maintaining optical fibers that do not form the fused and extended portion]. In addition, in this polarization maintaining optical fiber coupler, in the fused and extended portion, the stress applying portions are enveloped by the cladding. Moreover, polarization maintaining optical fibers are used in which the distance between adjacent outer circumferences of the two stress applying portions is 20 μm or more.

    摘要: The polarization-maintaining optical fiber 10 of the present invention is designed so that a plurality of core portions 12a,12b which have a high refractive index is provided in parallel along a single diameter direction in the cross section of the optical fiber, these core portions 12a,12b cooperating to propagate a single fundamental mode. In the production method for the polarization-maintaining optical fiber of the present invention, a plurality of holes 22 are formed longitudinally in parallel along a single diameter direction of a glass rod 21 having a low refractive index which forms the cladding, glass rods 23 for core use having a high refractive index which form the core portions are inserted into these holes 22, heating to form a unitary body is carried out, creating a preform which is then drawn. Further, the rare-earth-doped polarization-maintaining optical fiber of the present invention uses a rare earth element to dope the optical waveguide portion of the polarization-maintaining optical fiber, and can be employed in a light amplifier or laser oscillator. Moreover, the polarization-maintaining optical fiber coupler of the present invention is formed by bringing two or more polarization maintaining optical fibers into contact, heating, fusing and elongating them, and heating the vicinity of the connection point before and after connection.

    摘要: A low-cost fabrication technique, readily extensible to volume manufacturing is presented for an electrooptically active fiber segment that can be simply integrated into optoelectronic devices. The fabrication technique offers a dielectric isolation structure surrounding the fiber to allow high field poling, a pair of electrodes used both for poling and for inducing an electrooptic effect, and ends of the fiber unaffected by the fabrication and available for splicing with additional fiber sections. The technique is readily adaptable to specialized electrode structures including striplines and/or microstrip lines for high frequency applications and segmented electrodes for quasi-phasematched three-wave mixing applications. By combining the electrooptically active fiber segment with other fibers in an integrated fiber modulator, high frequency modulation of an optical signal may be achieved with applications in telecommunications. By including a Bragg grating structure in the same fiber segment, a remotely accessible electric field sensor is achieved. Three-wave mixing processes in the electrooptically active fiber segment will allow the generation of additional coherent radiation sources in both the visible/UV and infrared spectral ranges.

    摘要: Disclosed is a polarization-splitting fiber coupler capable of stably executing a polarization separation/coupling and a method of stably manufacturing the polarization-splitting fiber coupler at a low cost. The method comprises the steps of (1) arranging a plurality of non-polarization fibers in parallel so that the side surfaces thereof come into contact to each other; (2) heating and fusing a portion of the arranged non-polarization fibers by controlling a heating temperature and a heating time so that the cross section of the fused portion thereof has an aspect ratio of 1.85-1.95; (3) thereafter, forming a fused/drawn portion by drawing the fused portion while keeping the aspect ratio after lowering the heating temperature; and (4) connecting polarization-maintaining fibers to the respective ends of the fused/drawn portion, respectively. Further, a portion of the connected polarization-maintaining fiber is heated and drawn to a taper-shape to provide the heated-fused portion with a polarizer function.

    摘要: During the process of manufacturing polarization-selective fused-fiber couplers (1) having two or more input fibers and two or more output fibers and formed in the coupling region (fused region 6) from parallel, nonbirefringent, matched-cladding single-mode fibers, prior to the fusion of the fibers, linearly polarized light with a selected wavelength is fed into one of the input fibers (2) and detected at the ends of the two output fibers (3). The fibers are thereupon fused together with the coupler (1) being drawn until the coupling between the two fibers ceases to fluctuate. The source of heat is then turned off. With the method it is possible to manufacture fused-fiber couplers (1) whose lengths are only approximately 10 mm to 15 mm.
