| titleOfInvention | A kind of N × N array waveguide grating light wavelength router reducing frequency departure |
| abstract | The utility model discloses a kind of N × N array waveguide grating light wavelength router reducing frequency departure.It comprises N bar input waveguide, input waveguide zone, Waveguide array district, exports waveguide zone and N bar output waveguide; The Rowland circle structure tilted is adopted to introduce length difference in input waveguide zone and output waveguide zone, the Free Spectral Range eliminating traditional array waveguide optical grating light wavelength router requires and the contradiction that the order of diffraction time cannot realize for integer simultaneously, solve the problem that deviation appears in Free Spectral Range, thus reduce the frequency departure of output channel.The utility model is not changing each ingredient of traditional array waveguide optical grating light wavelength router, do not introduce on the basis of additional devices simultaneously, solve the problem of traditional array waveguide optical grating light wavelength router output wavelength frequency of occurrences deviation, be applicable to the waveguide material based on silicon dioxide, indium phosphide and silicon etc. and waveguiding structure, have and make simple, low cost and other advantages. |
