摘要： Two AWG circuits are integrated while preventing degradation in quality of a multiplexing/demultiplexing function. An arrayed waveguide grating circuit includes: a first slab waveguide (52) connected to a first input waveguide (51a) and second output waveguides (55b); a second slab waveguide (54) connected to first output waveguides (55a) and a second input waveguide (51b); and an array waveguide (53) connecting the first slab waveguide (52) and the second slab waveguide (54), wherein the input waveguides (51a, 51b) are connected to the slab waveguides (52, 54) at an interval of 1.5× from the outermost second output waveguide out of the second output waveguides (55a, 55b) connected at an interval x depending on a wavelength.

摘要： An arrayed waveguide grating type optical multiplexer/demultiplexer circuit in which wavelength dispersion is reduced. An input wave guide (1), a first slab waveguide (2), an arrayed waveguide (3), a second slab waveguide (4) and an output waveguide (5) are connected sequentially. Furthermore, a parabola waveguide (6) is provided between the input waveguide (1) and the first slab waveguide (2), and a taper waveguide (7) is provided between the second slab waveguide (4) and the output waveguide (5). A parabola waveguide length Z0 exists in a range Za,0=Z0=Zp,0 determined by a parabola waveguide length Za,0 where the ratio of absolute amplitude between the main peak and the first side peak in the field distribution of far-field of the parabola waveguide (6) has an upper limit of 0.217, and a parabola waveguide length Zp,0 where the relative phase of the main peak and the first side peak in the field distribution of far-field has a lower limit of 3.14 radian.
