摘要： An integrated optic polarization splitter (2), includes a pair of waveguide elements with a first waveguide element (10) having a horizontal orientation and a second waveguide element (12) having a vertical orientation formed from a plurality of waveguide core layers. The first and second waveguide elements are intersected or nearly intersected at one end of the structure and separated at the other end of the structure and the transition there between is made to be adiabatic. The waveguide elements receive an optical signal having both a TE component and a TM component. The TE component propagates along the horizontally oriented waveguide element (10) and the TM component propagates along the vertically oriented waveguide element (12).

摘要： A spectral polarisation separator (SPS) designed to separate two wavelength-separated signals applied to the SPS with the same state of polarisation (SOP) into signals with orthogonal SOP's comprises two or more birefringent fibre elements (1, 2) optically in series. The differential delays and relative orientations of these elements are chosen so that polarisation separation is effected without introducing any polarisation mode dispersion (PMD). This contrasts with a prior art single birefringent element SPS whose operation necessarily does introduce PMD.
A particular application for the SPS is in a dual wavelength transmitter designed for overcoming polarisation hole-burning effects in a long-haul optically amplified transmission system.

摘要： A polarized wave holding optical fiber (10) of the present invention includes a plurality of core portions (12a, 12b) in a high refractive index region that are juxtaposed in a radial direction of an optical fiber, and three core portions (12a, 12b) integrally propagate one fundamental mode. A method of producing a polarized wave holding optical fiber according to the present invention comprises forming a plurality of holes (22) in parallel with one another on a diameter of a glass rod (21) having a low refractive index as a clad, inserting glass rods (23) having a high refractive index as core portions into these holes (22), heating and integrating them together to form a base material, and melt-spinning the base material. A polarized wave holding optical fiber containing a rare earth element according to the present invention is formed by adding a rare earth element to a waveguide portion of the polarized wave holding optical fiber, and an optical amplifier and a laser oscillator utilize this polarized wave holding optical fiber. A polarized wave holding optical fiber coupler according to the present invention connects at least two polarized wave holding optical fibers, and heats, fuses and stretches them. The connection method comprises heating portions near the coupling point before and after connection.

摘要： An optical waveguide device formed out of a material the refractive index of which has anisotropy, and an optical instrument using the same device. The device comprises an electrooptic single-crystal substrate on which are formed a first core portion the refractive index of which is higher than that of the substrate with respect to both ordinary and extraordinary rays of light, and a second core portion the refractive index of which is higher than that of the substrate with respect to extraordinary rays of light only. The overlapping region of the first and second core portions constitutes a double mode waveguide for extraordinary rays of light. This optical waveguide device is used in place of a pinhole element in an optical system in a confocal scanning optical microscope so as to guide illuminating light into an object to be detected, and to guide the reflected light from the object into a detector. This microscope is provided with a polarization conversion element for use in setting the polarization direction of illuminating light different from that of reflected light. The optical waveguide device functions as a single-mode waveguide with respect to illuminating light, and as a double mode waveguide with respect to reflected light.

摘要： An overclad fiber optic coupler of the type wherein a plurality of optical optical fibers, each having a core and a cladding, are fused together along a portion of the lengths thereof to form a coupling region. Surrounding the coupling region is a matrix glass body of refractive index n3 which is lower than the fiber cladding refractive index n₂. The body has an inner region adjacent the optical fibers, an outer region having a radius greater than that of the inner region, and a transition region between the inner and outer regions. The softening point temperature of the inner region is greater than that of the outer region. The coupler exhibits both low polarization dependent loss and low excess loss.
