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： A fiber-type optical coupler has two optical fibers including a core on which a slanting Bragg diffraction grating is formed and a first cladding and a second cladding bordered with a boundary plane close to the core. The two optical fibers are placed by approximating the boundary plane almost contacting the core, making respective optical axes almost parallel and also making slanting directions of the respective Bragg diffraction gratings almost parallel. A wave vector of the slanting Bragg diffraction grating is located in a plane made by a normal set up on the boundary plane almost contacting the core and the optical axis of the core, and an angle θ made by the wave vector and the optical axis is 0 degree

摘要： The present invention is related to an optical multiplexer/demultiplexer that has a wide wavelength passing band. This optical multiplexer/demultiplexer includes a substrate formed from a material with a uniform refractive index, a first and a second waveguide which are mounted to the substrate and are formed from a material with a refractive index higher than the substrate, and a directional coupler that is formed by placing each portions the first and second waveguides in close proximity to each other at a preselected length. Each of the portions of the first and second waveguides which are in close proximity are bisected into an upper region and a lower region in the one direction the light waves propagate. The propagation constant of the upper region of the first waveguide is set to be higher than the other portion and the propagation constant of the lower region of the second waveguide is set to be higher than the other portion. This allows expansion of the wavelength passing band.
