Abstract
A waveguide structure and a method for splitting light is described. The method may include optically coupling a first waveguide and a second waveguide, where the optical coupling may be wavelength insensitive. The widths of the first and second waveguides may be non-adiabatically varying and the optical coupling may be asymmetric between the first and second waveguides. A gap between the first and second waveguides may also be varied non-adiabatically and the gap may depend on the widths of the first and second waveguides. The optical coupling between the first and second waveguides may also occur in the approximate wavelength range of 800 nanometers to 1700 nanometers.
