Abstract A novel modified Rowland grating structure is proposed in this paper. Optical filters with the proposed structure are designed and fabricated with both high input and output angles. The passband width, coupling loss of the filters are investigated as a function of the output waveguide width. Nearly aberration free diffraction filters with an ultracompact footprint less than 0.5 mm 2 were obtained with the proposed structure.
