The second layer which is less likely to be wetted has such a curved shape that the closer an end 3c becomes to the side surface 3s, the larger the distance from the first projection 4 becomes, and is extended as far as an upper end of the first layer 32, having the hard-to-get-wet first surface exposed.

摘要： PROBLEM TO BE SOLVED: To solve such a problem of an optical amplifier using a planar optical waveguide that since means for reflecting a signal light are provided on a first end face perpendicular to the boundary surface between a core layer and a clad layer of the planar optical waveguide, and on a second end face facing the first end face not in parallel therewith, manufacture of the planar optical waveguide is difficult technically and the manufacturing cost is high.SOLUTION: Since a first end face 210 is formed to incline from the upper surface to the lower surface, signal light 110 incident from the outside is reflected totally to propagate on a core layer, and the signal light 110 thus propagated is reflected, on the second end face 211, totally and externally upward or internally of a planar optical waveguide 10. Consequently, means for reflecting the signal light is not required, manufacture is facilitated and the cost can be reduced.
