摘要： An optical multiplexer/demultiplexer having a high isolation characteristic, a small polarization dependency and capable of being reduced in size is disclosed. An end portion of a core (15) and an end portion of a core (16) are arranged in opposed relation to each other with a thin-film filter (19) interposed therebetween. The end portion of the core (15) far from the filter and the end portion of the core (16) far from the filter are arranged in substantially parallel to each other. The core (17) is arranged in such a manner as to branch from the filter-side end portion of the core (15) and to be optically coupled with the core (15). The end portion of the core (15) near to the filter and the end portion of the core (16) near to the filter are curved. The end portion of the core (15) near to the filter is curved towards the core (17). The end portion of each of the core (15) and the core (16) far from the filter reaches an end of an optical waveguide substrate, and the end portion of the core (17) far from the filter reaches a side of the optical waveguide substrate.

摘要： By judicious engineering of grating parameters such as tooth shape, duty cycle and phase offset, the grating strengths and effective indices of the polarization modes of a grated waveguide are adjusted over a wide range of values to achieve a desired level of polarization sensitivity, or insensitivity. In the typical example, the physical geometry of the grating teeth is adjusted so that degenerate behavior (nTE = nTM and KTE = KTM) is obtained for two polarization modes; the effective refractive indices and grating strengths are matched for the TE and TM polarization modes. In the current embodiment the sidewall gratings are used in which the tooth profile is selected in order to equalize the grating strength for each polarization mode.

摘要： An optical waveguide device includes an LiNbO 3 substrate (26) and an optical waveguide (28) disposed on the LiNbO 3 substrate (26) by diffusing Ti therein. The LiNbO 3 substrate (26) has a step (80) on a surface thereof which corresponds to the area in which Ti is diffused. The step (80) has opposite side edges (80a) and a central area (80b) therebetween, the side edges (80b) having a height (Ts) greater than a height (Tc) of the central area (80b), whereby the side edges (80b) are raised higher than the central area (80b). The optical waveguide device has a relatively small coupling loss with respect to an optical fiber having a small light beam mode shape, thus eliminating optical device loss faults.

摘要： A micro-ring resonator includes: at least one first straight waveguide; a second waveguide (Arm3) and a third waveguide (Arm2), where the second waveguide (Arm3) and the third waveguide (Arm2) form a closed annular waveguide, and the annular waveguide is coupled to the first waveguide; a fourth waveguide (Arm1), where the fourth waveguide (Arm1) is coupled to the annular waveguide; and a polarization splitter (PS), where one end of the polarization splitter (PS) is connected to the fourth waveguide (Arm1), and one end is connected to the second waveguide (Arm3) in the annular waveguide. In the micro-ring resonator, a distance between two waveguides for separately transmitting different polarized light breaks a limitation of a resonator radius, and further, a distance between a TE path and a TM path is reduced.
