Abstract:
To provide an optical signal processing device that can collect light from an input waveguide to form a beam array having a small diameter. The optical signal processing device includes input waveguides 302a to 302c, an array waveguide 305 and a slab waveguide 304 that is connected to a first arc 304a having the single point C as a center and input waveguides 302a to 302c and that is connected to a second arc 404b having the single point C as a center and an array waveguide 305.
