| titleOfInvention | Temperature-insensitive flat-field type array waveguide grating router |
| abstract | The utility model discloses a flat field type array waveguide grating router insensitive to temperature. The device comprises an input coupling optical fiber array, an input waveguide, an input slab waveguide area, an array waveguide area, an output slab waveguide area, an output waveguide, an output coupling optical fiber array and a temperature compensation device; the flat field type arrayed waveguide grating router comprises a flat input field type and a flat focusing field type, and is designed based on an aberration theory; the temperature compensation device is arranged on an input waveguide or an output waveguide at the flat-field flat-plate waveguide end, and the input waveguide or the output waveguide is linearly moved along an input surface or an output surface in a passive or active mode according to temperature change feedback so as to compensate the influence of temperature, thereby realizing the temperature insensitivity. The flat field type array waveguide grating router insensitive to temperature can keep good linear dispersion and focusing effects, is flexible and convenient to control, and has a very high application prospect in a large-scale reconfigurable wavelength division multiplexing system. |
