摘要： PROBLEM TO BE SOLVED: To reduce crosstalk across adjoining optical circuits. SOLUTION: On a substrate, two or more main optical waveguides 2 and optical waveguides 3 for monitoring are arranged and vertical light path conversion mirrors 7 are formed to be opposed to the end parts of the optical waveguides 3, and thus, an optical tap circuit is made up. The vertical light path conversion mirrors 7 are formed by supplying a liquid curing resin 6 into mirror grooves 4 via two resin supply grooves 5. The liquid curing resin 6 also functions as a shading material. Since the resin supply grooves 5 and mirror grooves 4 formed into the state of parting the adjoining optical circuits from each other are filled with the resin as the shading material, the crosstalk across the adjoining circuits can be reduced due to the resin as the shading material.

摘要： PROBLEM TO BE SOLVED: To efficiently use waveform channel of a full-mesh optical WDM transmission system.
SOLUTION: Related to the light which is 8-wave multiplexed from eight output channels (p) of a wavelength circulation 8×8 optical multiplexor/demultiplexor 101a, an optical wiring part 101b allocates the light from the output channels (p) (p=1-7) to output ports (8-p), and allocates the light from an output channel (8) to an output port (8). The 8-wave multiplexed light is outputted from eight output ports (1)-(8) to WDN transmission/reception devices of output nodes No.1-No.8. The wavelength of light signal where an input node and an output node return to the same WDM transmission/reception device by wavelength routing, or autoregressive wavelength (loop back wavelength), is always set to be λ
8 (wavelength of optical signals A
i to H
i , with i=8). Due to characteristics of light reception sensitivity of a light receiving element, no practical problem occurs even if light reception sensitivity degrades at λ
8 of longest wavelength to degrade communication quality at wavelength channel of λ

摘要： PROBLEM TO BE SOLVED: To solve a problem in which a manufacturing yield is lowered through angular deviation of a 45° tilted mirror, in a vertical optical path conversion mirror circuit that makes light exit and enter from the optical waveguide of a planar optical circuit. SOLUTION: A mirror protection plate installed for protecting the vertical optical path conversion mirror is designed so that the exiting surface of the plate has a prescribed inclination to the planar circuit. Consequently, correction of the angular deviation of the mirror is made possible, which can realize the vertical optical path conversion mirror having high accuracy in the outgoing angle. Forming a tilted groove makes simple angular correction possible using conventional manufacturing equipment. Also, the angular correcting plate can realize angular correction that is simple and excellent in workability. COPYRIGHT: (C)2006,JPO&NCIPI
