摘要：

A novel type of waveguide coupler with a parallelogramic-shaped grating is investigated. Analysis shows that this type of coupler provides a stronger radiation factor and higher coupling efficiency than conventional sawtooth grating couplers. In addition, the radiation factor and the blaze angle of a parallelogramic grating can be independently designed.
