摘要： A photocoupler 3 splits the light from a low-coherence light source 1 into measuring light DL and local oscillator light KL. A photocoupler 5 receives measuring light DL and is input to an optical circuit 7 to be measured. The photocoupler 5 splits the reflected light RL. A polarization controller 9 controls the state of polarization of the reflected light RL as split by the photocoupler 5. A photocoupler 13 allows local oscillator light KL to be incident on a reflector mirror 16 and splits local oscillator light KL. A photocoupler 11 combines the reflected light RL as controlled in the state of polarization by the polarization controller 9, with the local oscillator light KL.

摘要： A guided-wave circuit with a phase adjusting plate which adjusts optical path length errors, occurring during the manufacture of PLC, by an additional processing performed after the production of the PLC; and a method for producing the guided-wave circuit. A guided-wave circuit with an amplitude adjusting plate which adjusts the amplitude characteristics of light by an additional processing performed after the production of the PLC; and a method for producing the guided-wave circuit. A guided-wave circuit with a birefringence adjusting plate which adjusts the birefringence of light by an additional processing subsequent to the manufacture of the PLC; as well as a method for producing the guided-wave circuit. The guided-wave circuit includes a groove crossing a plurality of waveguides constituting the optical waveguides, a plate having optical characteristics spatially changed so as to adjust the optical characteristics at the intersections of the plate with the optical waveguides when the plate is inserted into the groove, and an adhesive for fixing the plate in the groove. The guided-wave circuit also includes both of a phase adjusting plate and an amplitude adjusting plate to achieve further improvement in the optical characteristics. An apparatus for producing these optical characteristics adjusting plates is also included.

摘要： According to this invention, a superluminescent diode includes a current injection portion having a current injection electrode formed adjacent to a first end face, a light-absorption portion contiguous with the current injection portion; and a waveguide continuously formed to extend from the current injection portion to the light-absorption portion. The waveguide is constituted by an active layer and a member which completely buries the active layer, has a bandgap larger than that of the active layer, and is formed of a material having a small refractive index. The waveguide of the current injection portion is linearly formed to be perpendicular to the first end face. The waveguide of the light-absorption portion has an end portion for guiding reflected light in a direction different from a propagation direction of light propagating through the waveguide.
