| titleOfInvention | A kind of uniform arrayed-waveguide grating routers of loss |
| abstract | The utility model discloses a kind of uniform arrayed-waveguide grating routers of loss.Light is inputted from input waveguide, reach input star coupler, due to Kirchhoff's diffraction phenomenon, light field is expanded in input star coupler and is received by Waveguide array, the light that Waveguide array receives focal imaging into output star coupler behind Sinc function coupled zone；The Gaussian light field that Waveguide array transmits is transformed into Sinc function type light field by Sinc function coupled zone, so that exporting rectangle light field from output star coupler, realizes that uniform function is lost in arrayed-waveguide grating routers.The advantages that arrayed-waveguide grating routers of the utility model solve the intrinsic loss heterogeneity problem of arrayed-waveguide grating routers, have production tolerance big, at low cost, and crosstalk is small. |
