摘要： A directional coupler for coupling two single-polarization optical fibers each comprising a core, a cladding, and an elliptic jacket having a major axis is made by preparing two quartz substrates each of which is formed with a channel on one major surface; embedding and bonding the jacketed single-polarization optical fibers in the channels in the substrates, respectively, such that the major axis of the elliptic jacket extends perpendicular to the substrate surface; abrading away the substrates together with the fiber embedded therein from the major surface to a depth where light traveling in the core of said fiber may leak out; placing one substrate on the other substrate with the abraded surfaces facing each other; and bonding the substrates to keep the cores in sufficiently close relation to establish evanescent wave coupling therebetween. A stress perpendicular to the major axis is preferably applied to the fiber.

摘要： The present invention relates to an array waveguide grating and a method of manufacture thereof, in which a substantially smooth wavelength-loss characteristics is obtained in a pass band, rather than increasing the loss. In an array waveguide grating (10), wavelength multiplex division signal light is demultiplexed by a channel waveguide array (15), reflected by a Fabry-Perot resonator array (16), and passed through the channel waveguide array (15) again, so that a substantially smooth wavelength-loss characteristic is obtained in the pass band, rather than increasing the loss.

摘要： A width of a core in an optical waveguide is decreased in accordance with a value of a predetermined equation, as a distance of a position of the core to the center position thereof is decreased. Consequently, a rectangular spectrum property having no ripple is obtained on a lower wavelength side in a reflection grating. In addition, the width of the core is changed at the position Z in the direction of light propagation, while a UV light is radiated to the core, so that a periodically striated distribution of refractive indices having an envelope which is changed in accordance with a value of ".vertline.sin(C.multidot.Z).vertline./.vertline.C.multidot.Z.vertline." is formed in the core of the optical waveguide, and a phase of a light to be propagated in the direction of the light propagation is shifted at the position Z as defined below by .pi.. Z=m.pi./C(m=. . . ,-3,-2,-1,1,2,3, . . ) Thus, a rectangular spectrum property is obtained in a low reflection grating.

摘要： A diffraction grating of the present invention includes a first block (101) and a second block (102). The first block (101) is made up of a plurality of input waveguides (103), a slab waveguide (104), a delay waveguide array (105) and narrow grooves (106): each of which being filled with resin. The second block (102) is made up of a plurality of input waveguides (107), a slab waveguide (108) and a plurality of output waveguides (109). Since a circuit is cut off at the ends of the arrayed waveguides, a relative phase can easily be measured. The resin has undergone a refractive-index adjustment and compensates a phase error.

摘要： In an optical multiplexer/demultiplexer comprising optical multiplexer/demultiplexer circuits connected in multistage, the optical multiplexer/demultiplexer circuits each have two input ports and two output ports, an optical path, through which input optical signals with predetermined wavelengths are output after multiplexing and demultiplexing, varies depending upon the input port; the optical paths in each of the optical multiplexer/demultiplexer circuits have mutually opposite wavelength dispersion characteristics, and one of the optical paths in a first optical multiplexer/demultiplexer circuit is connected to one of the optical paths, in a second optical multiplexer/demultiplexer circuit, having wavelength dispersion characteristics opposite to the optical path in the first optical multiplexer/demultiplexer circuit. By virtue of this construction, an optical multiplexer/demultiplexer can be realized which causes no significant wavelength dispersion and, at the same time, has excellent wavelength flatness characteristics in passband.

摘要： A waveguide type grating device according to the invention includes a quartz substrate, a cladding and two waveguides. Waveguides are arranged to provide an input port, an Add port, an output port, a Drop port, directional 3 dB couplers, core width-changing portions, and grating portions each interposed between core width-changing portions. The width of core is changed between each non-grating portion and each grating portion in an adiabatic structure, for example, a parabolic structure. For this structure, a waveguide type grating device is structured to suppress the increase in wavelength loss due to coupling from progressive propagation mode to regressive radiation mode, with less cost and smaller dimension.

摘要： An optical device having a switching function has a waveguide filter for switching whether input signal light of including at least one specific wavelength should be transmitted or reflected. The input signal lights of wavelength of .lambda..sub.1 .about..lambda.n are transmitted to the input waveguide. When the waveguide filter is off, the signal lights of all wavelength are transmitted to the output port. When the waveguide filter is on, the signal light of wavelength of .lambda..sub.2 .about..lambda.n are transmitted, but the signal light of wavelength of .lambda..sub.2 is reversed and output to the drop port. If the thin film heaters are off, a signal light of wavelength of .lambda..sub.1 is output (dropped) from the drop port. If the thin film heaters are on, it is reversed and transmitted to the output port.
