ABSTRACT:
A planar lightwave circuit having an optical filter, which comprises: a first waveguide; a second waveguide separated from the first waveguide, in which the width of a first cross-section opposite to the first waveguide is wider than that of a second cross-section of the other side; and a trench located between the first and second waveguides, in which the optical filter is positioned.
