摘要：
A planar optical device useful as a low order wavelength router is realized by using a waveguide grating comprising two curved arrays of opposite curvatures. The diffraction order is determined by the angles of rotation of the two curved arrays, and any nonzero order less than about 30 can be realized. This arrangement is smaller, and performs better than a previous grating using a combination of three curved arrays.
