Claim:
1. An optical signal processing device including a waveguide formed on a substrate, comprising: an input waveguide, an array waveguide, and a slab waveguide having at least one first arc provided around a single point as a center connected to the input waveguide, and a second arc provided around the single point at a center connected to the array waveguide, wherein an output end of the input waveguide is formed in the direction of the single point such that an optical signal outputted to the slab waveguide reaches a face of the second arc of the slab waveguide, and a beam diameter at the face of the second arc of the slab waveguide is based on a first radius of the first arc and a second radius of the second arc.
