| PCT No. PCT/GB90/00765 Sec. 371 Date Jan. 2, 1991 Sec. 102(e) Date Jan. 2, 1991 PCT Filed May 17, 1990 PCT Pub. No. WO90/14316 PCT Pub. Date Nov. 29, 1990.A need often arises for micro-optical components, such as optical fibres and couplers, and micromechanical components with complex cross-sections which are different at opposite ends or, for directional couplers, at points along the length of the couplers. In the present invention, a soluble material 38 is added to at least one primary preform 35 to make a secondary preform 37 of circular cross-section. The secondary preform is then drawn to reduce the cross-section of the primary preform as required but the cross-sectional shape of the secondary preform is preserved. The soluble material is then removed and then part of the resulting product is heated and plastically deformed to give the required different ends 39 and 40 or other different cross-sections. In another aspect of the invention two soluble materials are used with different solubilities. After the most soluble material has been removed, an operation involving the less soluble material can be carried out, and then the less soluble material is at least partially removed. | ||||||

| PURPOSE:To easily couple intensive light and to transmit it to a distant place by decreasing at least the diameter of a core in an axial direction gradually from one end to the other end and increasing the refractive index of the core gradually in the direction of the decrease in core diameter. CONSTITUTION:At least the diameter of the core 42 between the diameter of a fiber 41 and the diameter of the core 42 decreases axially and gradually from one end to the other end and the refractive index of the core 42 increases gradually in the direction of the decrease in the diameter of the core 42. Then when one end where the diameter of the core 42 is large is used as an incidence end, intensive light can be coupled with high efficiency. Further, the core of this nonlinear optical fiber 41 becomes this in the axial direction, so as incident light is propagated, the light enters an area where the gain of induction Raman scattering is high. Consequently, the light can be transmitted efficiently to a distant place. | ||||||

| PURPOSE:To hold the direction of the optical main axis of a maintaining optical fiber constant by making the coating layer of the optical fiber not circular, but, for example, elliptic. CONSTITUTION:A clad layer 2 is formed around a core 1 and its periphery is coated with an elliptic jacket layer 3 and a substrate 5 to form the polarization plane maintaining optical fiber, which is covered with the coating layer 4 which has flat section. In this case, there are two main axes, which are installed in the lengthwise direction of the coating layer 4 as shown in figure (a) and figure (b). In either case, the optical fiber is wound invariably as shown in figure (c) to uniform the main shaft in the invariably constant direction. | ||||||

| PURPOSE:To manufacture the titled optical fiber having stabilized dimensions and shape, in continuous form, by inserting a glass matrix for core and clad and a glass tube containing boron oxide into a quartz tube maintained at negative pressure, and heating and drawing the assembly. CONSTITUTION:A glass matrix composed of the glass 1a for core and the glass 2a for clad, is inserted together with the glass tube 3a for jacket 3a and containing >=5mol% of boron oxide, into the quartz tube 4a for supporting use. The inside of the quartz tube 4a is maintained at a negative pressure of 1-50mm.Hg based on its exterior part, and the tube is heated gradually from one end and drawn to effect the integration of the components. The glass tube 3a and the quartz tube 4a are formed to elliptic form, and the supporting part 4 is formed to elliptic or circular form in the course of heat drawing process, to obtain a polarization maintaining optical fiber composed of the core part 1, the clad part 2, the jacket part 3 and the supporting part 4. | ||||||

| PURPOSE:To control easily and accurately the outside diameter of an optical fiber having a noncircular cross section with simple equipment by drawing a preform having a noncircular cross-sectional shape while rotating it and by measuring the outside diameter of the resulting fiber immediately after drawing. CONSTITUTION:The tip of a preform 3 having a cross section similar to the noncircular cross section of an optical fiber 6 such as a flower-shaped multicore type fiber consisting of cores 1 and a clad 2 is heated with a heating furnace 5 while rotating the preform 3 in the direction of an arrow 4 to manufacture a multicore type optical fiber 6 by drawing with a winder 7. The outside diameter of the fiber 6 is measured with a device 8 for measuring the outside diameter with laser at a position just behind the drawing position. The measured value of the outside diameter of the fiber 6 which rotates together with the preform 3 is compared to the set value of the outside diameter corresponding to the rotational position, and the compared value is fed back to the drawing speed, etc. to control the outside diameter of the fiber 6. The preform 3 is preferably rotated at about 100- several 1,000r.p.m. | ||||||

| PURPOSE:To obtain an optical fiber which prevents twisting during drawing and enables the easy identification of the axial direction of polarization in the stage of connection by forming the outside shape of the support part in the outermost part into an elliptical shape having the long and short axes in the direction where the fast axis and slow axis of the core coincide. CONSTITUTION:The outside shape of a support 1 made of quartz glass is formed to an elliptical shape resembling to the outside shape of a jacket 2, and the long axis and short axis directions of the outside shape of the support 1 coincide respectively with those of the jacket 2. Such optical fiber for maintaining the plane of polarization enables the immediate estimation of the shape of the jacket 2 and the axial direction of polarization of a core 4 from the shape of the support 1; therefore, the easy matching of the directions of polarization and the optical transmission with good efficiency are made possible. In the case of drawing the fiber, the outside diameter of the optical fiber is measured in two directions, horizontally and vertically, and the fiber is monitored so as not to rotate, whereby the optical fiber for maintaining the plane of polarization is easily obtd. | ||||||
