Abstract
A wavelength filter has a low index waveguide, a high index waveguide and a grating for coupling therebetween. The high index waveguide is in horizontal proximity to said low index waveguide. The low index waveguide and said high index waveguide have substantially different geometries which result in substantially different indices. A method for fabricating the wavelength filter is also disclosed.
