摘要： A width of a core in an optical waveguide is decreased in accordance with a value of a predetermined equation, as a distance of a position of the core to the center position thereof is decreased. Consequently, a rectangular spectrum property having no ripple is obtained on a lower wavelength side in a reflection grating. In addition, the width of the core is changed at the position Z in the direction of light propagation, while a UV light is radiated to the core, so that a periodically striated distribution of refractive indices having an envelope which is changed in accordance with a value of ".vertline.sin (C.multidot.Z).vertline./.vertline.C.multidot.Z.vertline." is formed in the core of the optical waveguide, and a phase of a light to be propagated in the direction of the light propagation is shifted at the position Z as defined below by .pi.. Z=m.pi./C(m= - - - , -3,-2,-1,1,2,3, - - - ) Thus, a rectangular spectrum property is obtained in a low reflection grating.

摘要： A diffraction grating of the present invention includes a first block (101) and a second block (102). The first block (101) is made up of a plurality of input waveguides (103), a slab waveguide (104), a delay waveguide array (105) and narrow grooves (106): each of which being filled with resin. The second block (102) is made up of a plurality of input waveguides (107), a slab waveguide (108) and a plurality of output waveguides (109). Since a circuit is cut off at the ends of the arrayed waveguides, a relative phase can easily be measured. The resin has undergone a refractive-index adjustment and compensates a phase error.
