Abstract
Provided is a flat-top mode generating device. The flat-top mode generating device includes an input waveguide, a double-tapered structure connected to the input waveguide, and an input star coupler connected to the double-tapered structure. The double-tapered structure includes a first part having a first height hat is equal to that of each of the input waveguide and the input star coupler, and a second part disposed in the first part on the plane and having a second height that is less than the first height, the second part being tapered from the input star coupler toward the input waveguide.
