摘要： An optical coupler comprises a tapered waveguide formed so that a waveguide width may be narrower as going from a predetermined starting position toward an emission end of a light signal. A difference between a first coupling factor and a second coupling factor is set within a predetermined range. The first coupling factor is the coupling factor to a waveguide having the same width as that in a first position in an inherent mode in the case where the tapered waveguide is cut in the first position. A second coupling factor is the coupling factor to a waveguide having the same width as that in a second position where is separated at a predetermined distance from the first position along a direction toward the emission end in an inherent mode in the case where the tapered waveguide is cut in the second position.

摘要： The present invention relates to a device and a method for monitoring each of the propagated light beams that are propagated in each waveguide of an arrayed waveguide device and a method of fabricating the device. In the prior art, problems were encountered in deriving monitor light and photodetecting the derived monitor light within the waveguide substrate. In the present invention, waveguide directional couplers are formed in the spaces between the arrayed waveguides to derive a portion of the propagated light as monitor light. Cavities are provided at the ends of auxiliary waveguides connected to the directional couplers, and monitor light is guideded into these cavities. The monitor light, after being reflected upward or downward of the substrate by optical path conversion elements installed inside the cavities, is photodetected by photodiodes. The optical path conversion elements can be fabricated by inserting metal bumps into the cavities and then forming the bumps with a mold.

摘要： An arrayed waveguide grating for easily changing the ratio of distribution of an optical signal into the main optical signal and the monitored optical signal is disclosed. In the device, an optical signal incident on an input waveguide is input into an arrayed waveguide via an input-side slab waveguide and is divided into main optical signals having different wavelengths in the arrayed waveguide with respect to a diffraction order m (natural number), and the divided optical signals are transmitted through an output-side slab waveguide and converged on output waveguides. The device has monitoring waveguides for monitoring optical signals having corresponding wavelengths of the main optical signals, where the monitored optical signals are diffracted in the arrayed waveguide with respect to a diffraction order m+i or m−i (i is a natural number), and the arrayed waveguide has a taper structure in the vicinity of the joint of the arrayed waveguide and the output-side slab waveguide, in which the width of each waveguide gradually changes along the direction of light transmission so as to adjust the ratio of distribution into the main optical signal and the monitored optical signal.
